If a circuit has 8 volts of power and 4 ohms of resistance, what will the current equal?
Detailed Explanation
Current is measured in amps. The formula to use here is:
\(I = \frac{\mathrm{V} }{\mathrm{R} } = \frac{\mathrm{8} }{\mathrm{4} } = 2\)
\(I = \frac{\mathrm{V} }{\mathrm{R} } = \frac{\mathrm{8} }{\mathrm{4} } = 2\)
