The power P dissipated by a
resistance R carrying a current I with a
voltage drop V is:
P = V2 / R = VI = I2R
Similarly, the power P dissipated
by a conductance G carrying a current I
with a voltage drop V is:
P = V2G = VI = I2
/ G
The power P transferred by a
capacitance C holding a changing voltage V
with charge Q is:
P = VI = CV(dv/dt) = Q(dv/dt) = Q(dq/dt)
/ C
The power P transferred by an
inductance L carrying a changing current I
with magnetic linkage Y
is:
P = VI = LI(di/dt) =
Y(di/dt) =
Y(dy/dt)
/ L
