(a) charges flow steadily in one direction only.

(b) charges flow in one direction.

(c) charges steadily flow to and fro.

(d) charges flow to and fro.

To determine

The correct option for the statement “The difference between dc and ac in electrical circuits is that in dc”.

Answer to Problem 10RAT

The correct option for the statement “The difference between dc and ac in electrical circuits is that in dc” is option (a).

Explanation of Solution

The dc current stands for direct current, while ac stands for alternating current in the circuit. The power produces in power plants is ac and that supply is feed to the industries, homes and to other places.

The charges flow in ac moves to and fro and are not steady. It means the frequency of changing the direction of these charges in the circuit is very high as a person can’t see the blinking bulbs.

In dc charges flow steadily in one direction only, dc is the rectification product of ac and whose charges do not flow to and fro. Dc is more dangerous than ac as charges and does not flows to and fro, while in ac the direction of charges changes and also its magnitude rises and decreases with some function like cosine or sine, so it has the possibility to leave the person after an electric shock in an ac supply.

Conclusion:

Therefore, the correct option for the statement “The difference between dc and ac in electrical circuits is that in dc” is option (a).
