An electrical machine in which mechanical energy developed by a prime mover is converted to electrical energy. Generators are made in a wide range of sizes, from very small machines with a few watts of electric power output to very large central-station generators providing 1000 MW or more. All electrical generators utilize a magnetic field to produce an output voltage which drives the current to the load. The electric current and magnetic field also interact to produce a mechanical torque opposing the motion supplied by the prime mover. The electrical power output is equal to the mechanical input minus the electrical and mechanical losses.
