How to convert electric current in amps (A) to resistance in ohms (Ω).

You can calculate ohms from amps and volts or watts, but you can't convert amps to ohms since ohm and amp units represent different quantities.

The resistance *R* in ohms (Ω) is
equal to the voltage *V* in volts (V), divided
by the
current *I* in amps (A):

*R*_{(Ω)} = *V*_{(V)}* */* I*_{(A)}

So

ohm = volt / amp

or

Ω = V / A

What is the resistance of an electrical circuit that has voltage supply of 12 volts and current flow of 0.3 amp?

The resistance R is equal to 12 volts divided by 0.3 amp:

*R* = 12V / 0.3A = 40Ω

The resistance *R* in ohms (Ω) is
equal to the power *P* in watts (W), divided by the square
value of the current *I* in amps (A):

*R*_{(Ω)} = *P*_{(W)}* */* I*_{(A)}^{2}

So

ohm = watt / amp^{2}

or

Ω = W / A^{2}

What is the resistance of an electrical circuit that has power consumption of 30W and current flow of 0.5 amp?

The resistance R is equal to 30 watts divided by the squared value of 0.5 amp:

*R* = 30W / 0.5A^{2} = 120Ω
