Question

a)What is the structural deference of DC generator and AC generator.
b)Compare the energy change taking place in an electric motor and a DC generato​

Answer 1

In a DC generator, the electrical current flows only in one direction. In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less. In a DC generator, the coil through which the current flows rotate in a fixed field.
