The Power, in Watts, Dissipated as Heat in a Resistor $\quad P = 50$

Multiple Choice

The power, in watts, dissipated as heat in a resistor varies jointly with the resistance, in ohms, and the square of the current, in amperes.A 30-ohm resistor carrying a current of 1 ampere dissipates 30 watts.
How much power is dissipated in a 50-ohm resistor carrying a current of 8 amperes?

A) $\quad P = 50$ Watts
B) $\quad P = 8$ Watts
C) $\quad P = 3,200$ Watts
D) $\quad P = 5$ Watts
E) $\quad P = 40$ Watts
