Electric Circuit Equations
Here are three key electric circuit equations linking current I (amps), charge Q (coulombs), time t (seconds), voltage V (volts), energy E (joules) and resistance R (ohms):
I = Q / t
current = charge / time
V = E / Q
potential difference = energy / charge
R = V / I
resistance = porential difference / current
Power:
P = E / t
power = energy / time
P = IV
power = current × voltage
P = I2R
power = current squared × resistance
P = V2 / R
power = voltage squared / resistance
Energy:
E = IVt
energy = current × voltage × time
E = I2Rt
energy = current squared × resistance × time
E = V2t / R
energy = voltage squared × time / resistance
E = VQ
energy = voltage × charge
