The conductivity of any conductor depends on which factors? The conductivity of any conductor depends on the type of element and temperature. Commonly, metals are good conductors. On the other hand, non-metals are not good conductors. On the other hand, non-metals are not good conductors. Again, with the increase in temperature the conductivity of conductors … Read more
What is a variable? The type of resistance, whose value can be changed within a certain limit, is called variable resistance. Its resistance can be changed as per requirement.
What do you understand by 1 V potential difference? 1 V potential difference means that when the 1-coulomb charge is transferred from one end of the conductor to the other, 1 Joule work takes place.
What is the voltage of the ground wire? The voltage of the ground wire is zero.
What is a kilowatt-hour? Kilowatt-hour is a unit of work or energy. The work done by a device of 1 kilo-watt power in one hour is called one kilowatt-hour.
What do you understand by 1 W of electricity? At 1 V voltage difference, if 1 A current flows through a device then the power of that circuit is 1 W.
What is the series connection? When the components of the circuit are connected one after another then the circuit is said to be in a series connection.
What is the law of cross-sectional area for resistance? At constant temperature, if the length of a conductor is kept constant then the resistance of that conductor is proportional to the cross-sectional area of that conductor.
