What is difference between AC current and DC current?

In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.

Which current is in Battery AC or DC?

Because the electrons flow in one direction only, batteries producedirect current. With Edison's direct current system, electricity was produced not by batteries but by a DC generator. The generator actually produced alternating current, which was then converted todirect current with a commutator.

Is a house AC or DC current?

Many other combinations of voltage and utility frequency were formerly used, with frequencies between 25 Hz and 133 Hz and voltages from 100 V to 250 V. Direct current (DC) has been almost completely displaced by alternating current (AC) in public power systems, but DC was used especially in some city areas to the end
