What is difference between AC & DC current?

What is difference between AC & 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.

What is AC and DC in electricity?

Definition: Alternating Current (AC) is a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles. … Direct current (DC) is electrical current which flows consistently in one direction.

What is AC current and DC current with examples?

Examples in the sense the devices that works on AC and DC. AC have a frequency and no polarity . … Current produced by generators or Turbine are AC currents and the current we get from our HOME power sockets are AC current. Mostly Electrical appliances like FAN , Bulb , AC, Motors are works on AC current.

Why is AC used over DC?

The major advantage that AC electricity has over DC electricity is that AC voltages can be readily transformed to higher or lower voltage levels, while it is difficult to do that with DC voltages. Since high voltages are more efficient for sending electricity great distances, AC electricity has an advantage over DC.
