A wire of resistance R is stretched uniformly to double its original length. The new resistance will be:

A wire of resistance $R$ is stretched to double its original length. Its new resistance will be [H] [width=0.5\linewidth]{107.png}

A metal wire of \(1\) cm length and \(1\) mm radius has a resistance of \(3\times10^{-3}\ \Omega\). If a wire of the same metal of length \(3\) cm and radius \(0.5\) mm is drawn, the resistance of the wire is:

The resistance of a wire at 0°C is 20 Ω. If the temperature coefficient of resistance is \(5\times10^{-3}\), the temperature at which the resistance will be double of that at 0°C is:

The equivalent resistance of the circuit shown in the figure between points A and B is:

10 W is to be delivered to a device via a wire having resistance \(2\,\Omega\). If 20 V is the voltage across the device, the power wasted in the process is:

If each of the resistances in the circuit is 10 \(\Omega\), the resistance between terminals A and B is:
