Volts to Amps with Watts calculation formula

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

I(A) = P(W) / V(V)

Volts to Amps with Ohms calculation formula:

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

I(A) = V(V) / R(Ω)
