ALTERNATOR ON LOAD When the load connected to alternator varies, its terminal voltage also changes due to the following reasons: Voltage drop due to armature resistance The voltage drop caused by armature resistance per phase is IRa where I is the phase current. This drop, however, can be neglected practically. The effective resistance of the armature winding of generator is greater than the conductor resistance measured by direct current. Due to alternating current, the additional energy over purely I2R value is expended inside and outside. The main causes of this additional energy loss are:
