Problem

A 12 V12\,\text V battery is connected across a resistor. Owing to heating, the resistance becomes three times its initial value while the battery voltage remains unchanged. The power dissipated in the resistor now is (a) 33 times its original value (b) 19\dfrac{1}{9} of its original value (c) 13\dfrac{1}{3} of its original value (d) Unchanged
