Answer:

A) the current in AC electricity varies in magnitude and direction.

C) the voltage in AC electricity varies in magnitude and direction.

Explanation:

In DC current and voltage the direction of current will not change with time and it always remains the same.

So here in DC voltage and DC current the magnitude may change with time but the direction will always remain same

While in AC voltage and AC current the direction of AC will change with time

periodically.

So here magnitude and direction both will change in AC current and AC voltage.

so the correct answer is

A) the current in AC electricity varies in magnitude and direction.

C) the voltage in AC electricity varies in magnitude and direction.

Answer:

option <u>A</u>

Explanation:

AC stands for Alternating current and DC stands for Direct current. The main difference between AC and DC is that current changes direction in AC and not in DC. Actually the direction of flow of electrons reverses periodically. In direct current, the electrons flow in same direction.

Thus, option A is correct.
