Calculate the resistance of a circuit with a voltage of 12 volts and a current equal to 3 amps.

i dunno what subject this is but its 6th grade science

resistance = 4 Ω

Explanation:

Data Given:

voltage = 12 volt

current = 3 amps

Resistance of the circuit = to be calculated

Solution:

The resistance of the circuit can be calculated by Ohm's law formula.

Resistance have a unit that is ohm (Ω)

Ohm's formula

              R = V/I

Where

R = resistance

V = voltage

I = current

Put value in the above formula

              R = 12 volt / 3 amps

            R = 4 (volt/amps)

            R = 4 Ω

Unit of Resistance

R = volt / amps = Ω

So, resistance = 4 Ω
