Why is the voltage induced in an alternator AC rather than DC?
To Explain: Voltage induced in an alternator AC but not in DC.
Answer to Problem 8A
The voltage induced in an alternator AC because the magnetic field increases and turn is decreases.
Explanation of Solution
Introduction: Alternative voltage is a voltage that changes its direction in regular or each cycle.
Alternative voltage or alternative current is induced in rotating armature of a generator. Alternative voltage is induced because as the magnetic field increases, it decreases each turn.
Conclusion: As in the rotating armature magnetic field increase, each turn decrease, this induced the voltage.
