Ohm's Law

Ohm's Law states: Voltage (V) = Current (I) x Resistance (R)

Solving for Current

To find the current (I), we can rearrange the formula:

Current (I) = Voltage (V) / Resistance (R)

Calculation

* Voltage (V) = 120 volts

* Resistance (R) = 10 ohms

Current (I) = 120 volts / 10 ohms = 12 amps

Answer: A 120V power supply connected to a 10 ohm resistor will produce 12 amps of current.
