300% Explanation - If the current is increased by 100% then the current will become twice i.e 2I. The power dissipated through a resistor is given by P = I2R If the current is made twice then power dissipated will become four times. i.e. P' = 4 P The percentage increase in power is given as, `"Increase in power" = (4"P" - "P")/"P" xx 100%` = 300%
