V = Voltage I = Current R = Resistance P = Power Q = Charge E = Energy t = time Vp=Voltage in primary coil Vs =voltage in the secondary coil Np=number of turns of wire on the primary coil Ns = number of turns of wire on the secondary coil
V = IR Voltage = Current x Resistance P = VI Power = Voltage x Current Q = It Charge = Current x time E = VQ Energy = Voltage x Charge E = VIt Energy = Voltage x Current x time Vp/Vs = Np/Ns Voltage in primary coil/voltage in the secondary coil. number of turns of wire on the primary coil/number of turns of wire on the secondary coil. Total cost = number of units x cost per unit. Used for working out electricity bills
