### Ohms Law Calculator for DC circuits:

Using our ohm’s law calculator, you can find any value of current, voltage, resistance and power by entering any two values.

i.e if you enter the value of current 2 Amps and Voltage as 12 Volts then press the calculate button to get the remaining resistance and power values in the results box.

You get the result of resistance as 2 Ohms and Power as 72 Watts.

Also, you can change the value of value between micro to Mega. Also, our calculator gives you accurate results within a very short time.

### AC Complex Power calculator with Ohms for AC circuits:

Just enter any two value with the phase angle to get the complex power or impedance.

As you know in AC circuits, the impedance *Z*_{(Ω) }and the complex power *S*_{(VA) }of the circuit is purely depending on the phase angle.

The voltage is the multiplication of the current and impedance.

*V*_{(V)} = *I*_{(A)} × *Z*_{(Ω)} = *(|I|*×*|Z*|) ∠ (*θ _{I}* +

*θ*)

_{Z}Complex *S*_{(VA) }power is the multiplication of current and voltage. Then AC complex power S will be calculated from below formula.

*S*_{(VA)} = *V*_{(V)} × *I*_{(A)} = *(|V|*×*|I*|) ∠ (*θ _{V}* –
