- Electricity Equations
- power = voltage x current
- P = VI
- voltage = current x resistance
- V = IR
- charge = current x time
- Q = It
- energy = voltage x charge
- E = VQ
- energy = current x voltage x time
- E = IVt
- total cost = number of units x cost per unit
- voltage across primary coil/voltage across secondary coil = number of turns on primary coil/number of turns on secondary coil
- power = voltage x current
