In the circuit shown, a fixed resistor X is connected in series with a battery and a variable resistor.
The power dissipated in resistor X is 7.2 W when a current of 3.0 A passes through it.
The variable resistor is adjusted so that the power dissipated in X increases by 50%.
What is the new current in the circuit?
