Final answer:
The Laws of Electromagnetic Induction involve Faraday's Law and Lenz's Law. AC generators have advantages of higher efficiency in long-distance power transmission and lower maintenance requirements.
Step-by-step explanation:
Laws of Electromagnetic Induction:
- Faraday's Law: The induced emf in a circuit is directly proportional to the rate of change of magnetic flux through the circuit.
- Lenz's Law: The direction of the induced current is such that it opposes the change that produced it.
Advantages of AC Generator over DC Generator:
- AC generators are more efficient in transmitting power over long distances due to lower energy losses.
- AC generators do not require a commutator, which decreases the maintenance and reduces the chances of wear and tear.
