Can you explain Ohms Law?
Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage.
I ∝ V, I = V/R (resistance of the conductor)
Changes Of resistance with temparature: The resistance of all materials changes with changes in temperature. The resistance of all pure metal increases with temperature. The
