Ohm's law:

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

Current is constant.

V_{0} = iR

If the resistance in a circuit connected to a constant current is halved, how is the voltage in the circuit affected?

Select one:

a. The voltage is reduced by a factor of 4.

b. The voltage is quadrupled.

c. The voltage remains constant.

d. The voltage is reduced by a factor of 2.

e. The voltage is doubled.
