The question is unclear. Please provide more context.

Ohm's Law states that the voltage (V) in a circuit is equal to the current (I) multiplied by the resistance (R).

• V = I * R

• Voltage is measured in volts (V)

• Current is measured in amperes (A)

• Resistance is measured in ohms (Ω)

• Example: If a circuit has a current of 2A flowing through a resistance of 5Ω, the voltage would be 10V (2A * 5Ω = 10V)
