A current is flowing in a circuit consisting of a resistor and a battery.
What happens to the power dissipated in the resistor when the resistance is quadrupled and the voltage remains constant?
Let the voltage of the battery be and initial resistance be .
Thus, the initial power dissipated is
Now the resistance is quadrupled keeping the voltage constant i.e
New power dissipattion is
Hence the power dissipated is quartered.

When temperature of the conductor is increased, then the collision frequency between current carries ( electrons ) and atoms increases. This results in
wires (same length, same area, same material) are connected in parallel and each has resistance, then the equivalent resistance will be
The voltage - current graph of a metallic conductor at two different temperature and is shown below. At which temperature is the resistance higher?
Six identical cells, each of emf of , are connected in parallel. The net emf across the battery is
