What are the differences between DC current vs AC current?

Two types of current - 1.Direct current 2.Alternating current

Direct current Direct current flows only in one direction. Direct current vs Alternating current

DC electricity can be produced by a number of devices. Batteries Solar photo voltaic cells DC generators For gird DC must be converted to AC by inverter

DC electricity has following disadvantages Higher line loss Higher capital cost

Alternating current -AC

In an alternating current the electrons periodically reverse direction of flow through the material in one direction and then reverse their path and flowback in the other direction.This happens over and over again at a rapid rate.

Current changes direction 120 times per second.

AC produced by generators. Inverter can convert AC to DC Grid generally use AC power AC is easily converted from high to low voltage High voltage used for long distance transport Power reduced to lower voltage for customer equipment
