Question

A cellphone charger has a transformer with

2000 turns in the primary coil which converts 240v a.c to 6v a.c
and a rectifier that converts 6v a.c to 6v d.c. what do the letters a.c and d.c stand for?​

Answer 1

A.C → Alternating current.

D.C → Direct current

Step-by-step explanation:

A.C is an abbreviation for Alternating current.

Alternating current is a type of current that flows sinusoidally or current that changes direction with time.

D.C is an abbreviation for Direct current.

This type of current flows only in one direction, i.e it doesn't change direction with time.

A rectifier can be used to convert A.C to D.C, allowing it to flow in one direction.
