Electricity is distributed from electrical substations to neighborhoods at 1.6×104 V . This is a 60Hz oscillating (AC) voltage. Neighborhood transformers, seen on utility poles, step this voltage down to the 120V that is delivered to your house. How many turns does the primary coil on the transformer have if the secondary coil has 120 turns? No energy is lost in an ideal transformer, so the output power Pout from the secondary coil equals the input power Pin to the...

Suppose there are two transformers between your house and the high-voltage transmission line that distributes the power. In addition, assume your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:24) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 62.5 mA exists in the primary of the transformer. The secondary is connected to the primary of another step-down transformer (turns ratio =...
