Electric power:

$\overline{){\mathbf{P}}{\mathbf{=}}{\mathbf{V}}{\mathbf{i}}{\mathbf{=}}{{\mathbf{i}}}^{{\mathbf{2}}}{\mathbf{R}}{\mathbf{=}}\frac{{\mathbf{V}}^{\mathbf{2}}}{\mathbf{R}}}$

Using i and R:

P_{0} = i^{2}R

A circuit maintains a constant resistance. If the current in the circuit is doubled, what is the effect on the power dissipated by the circuit?

Select one:

a. The power dissipated remains constant.

b. The power dissipated is reduced by a factor of 2.

c. The power dissipated is reduced by a factor of 4.

d. The power dissipated is quadrupled.

e. The power dissipated is doubled.
