Question
how much voltage would be necessary to generate 11 amps of current in a circuit that has 7 ohms of resistance?
answer
what are the units for your answer?
select one:
amps
ohms
volts
Step1: Recall Ohm's Law
Ohm's Law is $V = I \times R$, where $V$ is voltage, $I$ is current, $R$ is resistance.
Step2: Plug in values
$I = 11$ amps, $R = 7$ ohms. So $V = 11 \times 7$.
Step3: Calculate result
$11 \times 7 = 77$. Voltage unit is volts.
