An electric current is the flow of electric charge through a conductor, such as a wire. It is an essential aspect of how electricity is used and transmitted in our modern world. There are several effects of an electric current that are important to understand, including its ability to produce heat, magnetism, and chemical reactions.

One of the most noticeable effects of an electric current is the production of heat. When an electric current flows through a conductor, it can cause the conductor to heat up. This is because the movement of the electric charges within the conductor creates a form of resistance, which can cause the conductor to become hot. This effect can be useful in a variety of applications, such as in electric heaters or in soldering irons. However, it can also be dangerous if the conductor becomes too hot, as it can cause fires or other accidents.

Another effect of an electric current is the production of magnetism. When an electric current flows through a conductor, it creates a magnetic field around the conductor. This is because the movement of the electric charges creates a magnetic force, which can attract or repel other magnetic materials. This effect is used in a variety of applications, such as in electric motors and generators, which use the magnetic force produced by an electric current to create mechanical energy.

Finally, an electric current can also produce chemical reactions. For example, an electric current can be used to break down water molecules into hydrogen and oxygen, a process known as electrolysis. This effect is used in a variety of applications, such as in the production of hydrogen fuel for vehicles. An electric current can also be used to produce chemical reactions in other materials, such as in the electroplating process, where a metal is deposited onto another surface using an electric current.

In conclusion, an electric current has a variety of effects that are important to understand and utilize in our modern world. It can produce heat, magnetism, and chemical reactions, which are used in a variety of applications, from electric heaters to hydrogen fuel cells. Understanding these effects is essential for the safe and effective use of electricity.

What do we mean by easier? Calculate the length of the wire making the coil given that its cross-sectional area is 1 × 10 -7 m 2 and resistivity 1 × 10 -6Ω m. The process again involves the transition of electrons between an excited state and a lower-energy state, emitting photons of light in the process. Let's look at a useful application of the heating effect. Here the metal ions are positive as the electrons are delocalised. The conventional symbol for drawing a fuse in a circuit diagram is shown here: A fuse. Pour one of the liquids into the beaker.

When the electron returns to its normal state, it emits a photon of light energy with energy specific to the gas being used. Measure the temperature of water at each battery stage. Put I2 on the horizontal axis X-axis. This can be done manually or take place automatically. Corrosion The process of electrolysis can cause corrosion in a number of ways discussed below.

The serious internal burns may prove dangerous. The polarities of both ends of the solenoid changes according to the direction of electric current passes. Electric current is dangerous because it is invisible. Do this carefully so that the carbon rod in the centre doesn't break. Many car parts, bathroom taps and wheel rims are electroplated with chromium.

Sensations of pain develop, and voluntary control of the muscles that lie in the current pathway becomes increasingly difficult. We can define this phenomenon as the heating effect of the electric current. Open switch An open switch breaks the circuit and prevents current in the circuit. Draw a circuit diagram in the space below with two bulbs, two cells, an open switch and a resistor. RCDs Residual Current Devices operate by detecting a difference between the current on the live wire and the current on the neutral wire. These current causes physical injury, however, heart and respiratory function continue well. Magnetic field of bar magnets repelling.

The current that flow is the same for all the devices. The specific heat capacity of water is 4200 J kg—1 K—1. Impure copper is connected to the positive electrode and the negative electrode consists of an initially thin piece of pure copper. If you are passing under a high voltage line you may notice a slight hiss. I am reliably informed that this is why birds prefer to sit on power-lines rather than on branches! An example of this is the common household light bulb. Here are 3 benefits of chemical effects of electric current. As there is so little resistance the current flows along the short circuit and doesn't pass through the main circuit.

In order to work out what they are, let's first remind ourselves about conductors and insulators. The plotting compasses changed direction when the current was switched on. This will require some practice. In the human body, hundreds of muscles control blood circulation, breathing, digestion, reflex actions and many other vital areas within the body. Examples of fair use include commentary, search engines, criticism, news reporting, research, teaching, library archiving and scholarship. The different effects of electric current and ways of minimising harmful consequences will be explored in this section.

When he turned the switch on, he noticed a spark at the plug, and at the same time, the lights went out. This heat is useful to us as it heats our water. The idea of conventional current and SI units and their importance will only be discussed in Grade 9. Now the connections of terminals of the cell of the lower emf is reversed, then the balancing length is obtained at 3 cm. This means that the force on CD is upwards and the coil electromagnet will turn clockwise continuously. Deflection of the compass needle changes due to the formation of a magnetic field.

One way to reduce the current while providing the same power is to increase the voltage. Make sure that you wrap the wire in the same direction. The scientist Michael Faraday discovered this for the first time. Next, turn one magnet around so that opposite poles are now facing each other and sprinkle the filings over the paper again. The element is a large resistor. INSTRUCTIONS: This answer will depend entirely on where the learner lives. Then compare the brightness of the light bulb with the previous brightness.

The inventor, Thomas Edison, experimented with thousands of different resistor materials until he eventually found the right material so that the bulb would glow for over 1500 hours. Parallel Circuits Unlike series circuits, the parallel circuit has different devices arranged in a specific manner. Concept map Complete the concept map to summarise what you have learned about electric circuits and the effects of an electric current in this chapter. X-ray effect of an electric current 5. The direction in which the electrons move, the current is in the opposite direction. Different learners in the same group may have different recycling centres closest to where they live.

You will realize that the anode has lost in mass while the cathode has gained in mass by an amount equal to the mass lost by the cathode. We are going to perform it again, this time focussing on the effects of an electric current. Earth has a magnetic field, as though there is a big bar magnet running through the core, with its South Pole under Earth's magnetic North pole. This isn't just to make them look pleasing to the eye. The use of a special device called a defibrillator is required to save the victim.
