DC power calculation

Voltage (V) estimation from modern-day (I) and opposition (R):

V(V) = I(A) × R(Ω)

Complex strength (S) estimation from voltage (V) and cutting-edge-day (I):

P(W) = V(V) &instances; 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) instances the impedance Z in ohms (Ω):

V(V) = I(A) &instances×Zcomplex electricity S in volt-amps (VA) is equal to the voltage V in volts (V) times the ongoing I in amps (A):

S(VA) = V(V) × I(A) = (times) ∠ (θV - θI)

The actual energy P in watts (W) is equivalent to the voltage V in volts (V) times current I in amps (A) times the energy detail (cos φ):

P(W) = V(V) × I(A) × cos φ

The receptive strength Q in volt-amps responsive (VAR) is equal to the voltage V in volts (V) times the continuing I in amps (A) period the sine of the complicated power degree factor (φ):

Q(VAR) = V(V) × I(A) × sin φ

The electricity element (FP) is equal to the outright genuinely really worth of the cosine of the tough electricity degree issue

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)t(s)
