Amajor difference between ac and dc electricity is that a) the current in ac electricity varies in magnitude and direction. b) the current in dc electricity varies in magnitude and direction. c) the voltage in ac electricity varies in magnitude and direction. d) the voltage in dc electricity varies in magnitude and direction.

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.
