Assertion : When current through a bulb is increased by `2%` power increases by `4%`
Reason : Current passing through the bulb is `prop (1)/(Resistance)`.

If the current in a electric bulb drops by 2% then the power decreases by

A current of 2A flows through a 12 V bulb then find resistance.

If the current through a resistor in a circuit increases by 3%, the power dissipated by the resistor

A bulb is marked 220 V and 40 W. Calculate the current flowing through the bulb and its resistance.

Assertion : The length of a simple pendulum is increases by 4% the corresponding decrease in time period will be 2% Reason : T = prop sqrt(1)

Assertion If current shown in the figure is increasing, then Reason IF current passing through an inductor is constant, then both ends of the inductor are at same potential.
