If the resistance of a certain copper wire is `1Omega`, then the resistance of a similar nichrome wire will be about:

The lengths radii and specific resistance of two conducting wires are each in the ratio of 1:3. If the resistance of the thinner wire is 10 Omega then the resistance of the other wire will be

Two wires are having length , resistivity and their radius in the ratio of 1:3 . Resistance of the thinner wire is 10 Omega , then the resistance of the other wire will be

The temperature coefficient of resistance of a wire is 0.00125 per .^oC . At 300K, its resistance is 1 Omega . The resistance of the wire will be 2 Omega at

The resistance of a wire is 5 Omega at 50^@C and 6 Omega at 100^@C . The resistance of the wire at 0^@C will be

Two resistances are joined in parallel of which equivalent resistance is 1.2 Omega . One of the resistance wire is broken and the effective resistance becomes 2 Omega , then the resistance of the wire that got broken was :

IF the length of a copper wire is increased by 0.1%, show that the resistance of the copper wire will increase by 0.2%.
