Question

Distinguish between D.C. and A.C.

Answer 1

	D. C.	A. C.
Definition	In DC, the current's direction doesn't change.	In AC, the direction of the current keeps reversing periodically.
Load Type	DC’s load is generally resistive in nature.	AC’s load is resistive, inductive or capacitive.
The direction of flowing electrons	In DC, the flowing electrons are unidirectional	The direction of flow of electrons in AC is bidirectional.
Frequency	DC's frequency is Zero.	AC's frequency is 50 or 60 Hz.
Transmission	We can transmit it over a long distance with negligible losses.	We can transmit it over a long distance with few losses.
Purpose	Used in electroplating, electrolysis, electronic equipment, and more.	Used in factories, industries, households.
Passive Parameter	Resistance	Impedance
