Ohm's law:

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

Solving for resistance:

$\overline{){\mathbf{R}}{\mathbf{=}}\frac{\mathbf{V}}{\mathbf{i}}}$, where V is the voltage and i is the current.

The current I in the main branch of the circuit shown is 25 Amps. The current I1 through resistor R_{1} is 5 Amps, and the current I_{2} through resistor R_{2} is 20 Amps. Does R_{1} or R_{2} have a higher value of resistance?

a. R_{1} is larger than R_{2}

b. R_{2} is larger than R_{1}

c. There is not enough information
