Question

Is the TV using direct current or alternating current?

Answer 1

Alternative Current:

1. It stands for alternating current.
2. Electrons in AC periodically alternate between moving forward and backward in direction.
3. The principal supply for the TV is designed to work with alternating current, which is available from power plants.
4. A television's bulk of parts operates on direct current.
5. Direct current is converted from the alternating current by rectifier circuits in televisions.
6. A rectifier is a piece of electrical equipment that changes alternating current (AC) (which frequently reverses direction) into direct current (DC) (which only flows in one direction).

Direct Current:

1. It stands for direct current.
2. Electric charge flow is one-way.
3. Electronics that rely on batteries, such as your smartphone or mobile device, are powered by the steady and constant voltage of DC electricity.
4. DC power's smooth, constant electrical current always flows between positive and negative terminals in the same direction, just like the battery powering your kids' remote-control car.

Consequently, most of the television's internal components run on direct currents. For converting alternating current to direct current, TVs use rectifier circuits.
