Why must we always use a transformer-rectifier when experimenting with electricity from a power plant?
Power plants produce electricity that is suitable for transport over the long distances between the plant ans our houses. Because of this there are two characteristics that make this electricity different from the electricity that we use in the day by day applications.
The first different characteristic is the high voltage of the electricity transported between plant and our homes. The high voltage requirement used in the transport wires between plant and homes is given by the necessity to keep the currents low enough (to not...
