Select calculation type, 输入 amps and watts or ohms and press the 计算 button to get volts:
The voltage V in volts (V) is equal to the power P in watts (W), divided by the current I in amps (A):
V(V) = P(W) / I(A)
The voltage V in volts (V) is equal to the current I in amps (A), times the resistance R in ohms (Ω):
V(V) = I(A) × R(Ω)
