DC power calculation
Voltage (V) estimation from cutting-edge (I) and opposition (R):
V(V) = I(A) &instances; R(Ω)
Complex energy (S) estimation from voltage (V) and modern-day (I):
P(W) = V(V) × I(A) = V 2(V)/R(Ω) = I 2(A) × R(Ω)

AC power calculation
The voltage V in volts (V) is eqaul to the persevering with I in amps (A) times the impedance Z in ohms (Ω):
V(V) = I(A) &instances×Zcomplicated power S in volt-amps (VA) is equal to the voltage V in volts (V) times the continued I in amps (A):
S(VA) = V(V) &instances; I(A) = (times) ∠ (θV - θI)
The actual power P in watts (W) is equivalent to the voltage V in volts (V) instances contemporary I in amps (A) times the power element (cos φ):
P(W) = V(V) × I(A) × cos φ
The receptive strength Q in volt-amps responsive (VAR) is same to the voltage V in volts (V) instances the persevering with I in amps (A) period the sine of the complicated energy level point (φ):
Q(VAR) = V(V) &instances; I(A) &instances; sin φ
The electricity detail (FP) is equivalent to the outright really worth of the cosine of the difficult strength level factor

Energy & power calculation
The ordinary energy P in watts (W) is equal to the power fed on E in joules (J) separated by means of the use of time span Δt in seconds (s):
P(W) = E(J)/Δt(s)
