Question

Explain alternating current and direct current. Include two ways that they are alike and one way that they are different.

Answer 1

Answer:

Direct current Alternating current

1 D.C flows in one direction in the circuit A.C reverses its direction while flowing in the circuit.

2 The frequency of the direct current is zero. The frequency of alternating current is 50Hz or 60Hz depending on the country.

3 For eg: Current from Cell or Battery. For eg: Current from A.C Generator and mains.

4 The voltage of DC cannot travel very far until it begins to lose energy. Safe to transfer over longer city distances

5 Electrons move steadily in one direction. Electrons keep changing directions.

6 It is the current of constant magnitude. Magnitude of current varies with time in A.C
