Question:

# The electric power consumed by an electric kettle is 2000 W. If the voltage being supplied to the kettle increases 4 times and the current flowing through the kettle is decreased by half, what would be the effect on the power consumed by the kettle?

A The electric power would double.
explanation

The formula of finding electrical power is P=VI. If the voltage increases 4 times and the current flowing through the kettle becomes half then $P = 4V \times \frac{\mathrm{1} }{\mathrm{2} }I = 2$ (PI). The electric power of the electric kettle would become double.
