(b) 200%
(d) 400%
(c) 300%

Answer:
300%
Expalination:
When a current I is flowing through a resistor of resistance R , the power dissipated across it can be calculated as P=I2R . Hence, on increasing the current by 100% , the power dissipated across the resistor increases by 300% which corresponds to (C).
