Question

differentiate between DC and AC​

Answer 1

Answer:

ALTERNATING CURRENT : (AC)

AC can be converted easily into dc by using Diodes(rectifier)

AC Generation is more economical than dc

AC can be stepped up or down by using transformers.

AC can be transmitted to distant places without any significant line loss.

AC can be reduced by using choke coil without any significant wastage of energy.

DIRECT CURRENT:(DC)

DC cannot be stepped up or down by using transformers.

Due to steady current no change in flux is noted.

Frequency of DC is zero.

220V DC is less danger compared to 220V AC
