Question

(i) What is an AC generator or dynamo used for?

(ii) Name the principle on which it works.

Answer 1

Step 1: Use of an AC generator

1. The AC generator or dynamo can be used to convert mechanical energy to electrical energy.
2. The AC Generator’s input supply is mechanical energy supplied by steam turbines, gas turbines, and combustion engines. The output is an alternating electrical power in the form of alternating voltage and current.

Step 2: Principle on which ac generator works

1. Faraday's law of electromagnetic induction is used as a working principle for AC generators.

Step 3: Final Answer

1. An AC generator or dynamo is used to convert mechanical energy to electrical energy.
2. Faraday's law of electromagnetic induction is the principle on which it works
