Ohm's law:

$\overline{){\mathbf{V}}{\mathbf{=}}{\mathbf{i}}{\mathbf{R}}}$

i_{0} = V/R

Resistance is constant

If the voltage across a circuit of constant resistance is doubled, how is the current in the circuit affected?

Select one:

a. The current is doubled.

b. The current is reduced by a factor of 2.

c. The current is quadrupled.

d. The current is reduced by a factor of 4.

e. The current remains constant.
