"The resistance of a wire is 1 ohm. Explain the meaning of this statement.
The resistance of a wire is 1 ohm, it means a current of 1 ampere will flow through the wire when the potential difference across it is 1 volt.
1.A copper wire has diameter 0.5mm & reactivity of 1.6*10 to the power -8 ohm m.what will be the length of this wire to make its resistance 10 ohm ? How much does the resistance charge if the diameter is doubled?
The temperature coefficient of resistance of a wire is 0.00125 per °C. At 300 K, its resistance is 1 ohm. This resistance of the wire will be 2 ohm at (IIT-JEE 1980)
