### Ohms calculations

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

So The resistance R in ohms (Ω) is equal to the squared voltage V in volts (V) divided by the power P in watts (W).

So The resistance R in ohms (Ω) is equal to the power P in watts (W) divided by the squared current I in amps (A).

### Amps calculations

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

So The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V).

So The current I in amps (A) is equal to the square root of the power P in watts (W) divided by the resistance R in ohms (Ω).

### Volts calculations

So The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω).

So The voltage V in volts (V) is equal to the power P in watts (W) divided by the current I in amps (A).

So The voltage V in volts (V) is equal to the square root of the power P in watts (W) times the resistance R in ohms (Ω):
