Question 23
What is the difference between a direct current and an alternating current? How many times does AC used in India change direction in one second?

Answer 1

The difference between a direct current and an alternating current:

$\begin{array}{cc}\text{Direct Current}& \text{Alternating Current}\\ \text{1. In Direct current, the direction of current remains fixed over the whole time.}& \text{In Alternating current, the direction of current keeps on changing at regular intervals.}\end{array}$

In India, the AC changes its direction 100 times in one second.
