📐 The Maths

Circuit: OPEN

Ohm's Law

Circuit
V=IR (volts = current * resistance)

V = 0.00A * Ω

Circuit
I=V/R (current = volts / resistance)

0.00A = V / Ω

Circuit
R=V/I (resistance = volts / current)

Ω = V / 0.00A

Circuit
P = V * I (power = volts * current)

0.00W = 0.00V * 0.00A

Component
P = I² * R (power = current² * resistance)

0.00W = 0.00A² * Ω
