Understand DC and AC

English cover.jpg

The meaning of direct current is direct current, also known as constant current. Constant current is a type of direct current that remains constant in size and direction, while alternating current refers to alternating current, which is a current whose direction changes periodically over time. The average current in a cycle is zero.

1. What is DC

It refers to the constant direction of voltage and current DC (Direct Current).

2. What is communication

Alternating Current t (AC) refers to the periodic variation of voltage and current in both direction and magnitude. The representative waveform of AC is a sine wave (s in), and commercial power sources use sinusoidal alternating current.
