Study Notes
Heating Effects of Electric Current
- When an electric bulb filament is heated, it glows, producing light.
- This heating effect is due to the resistance of the filament to the flow of electric current.
Factors Affecting Heat Production
- The amount of heat produced in a wire depends on the resistance of the wire, the current flowing through it, and the time for which the current flows.
Effects of Large Currents on Wires
- If a large current passes through a wire, it may melt or burn due to excessive heat produced.
Effects of Large Currents on Appliance Elements
- Large currents can cause the elements of some electric appliances, such as fuses, to melt or burn out.
Purpose of Using Different Wires
- Different wires with varying materials, lengths, and thicknesses are used in electric circuits to optimize their performance, safety, and efficiency.
