When temperature of the conductor is increased, then the collision frequency between current carries ( electrons ) and atoms increases. This results in

$10$ wires (same length, same area, same material) are connected in parallel and each has $1\Omega$ resistance, then the equivalent resistance will be

An alternating voltage$E=200 \sin (300 t)$ volt is applied across a series combination of $R=10 \Omega$ and inductance of $800\ mH$. Calculate the impedance of the circuit.

A wire has resistance of $12 \Omega$. It is cut into two parts and both have are connected in parallel. The new resistance is?
