Is the battery DC or AC?
1 Answers
The battery is DC. Here is the extended content: 1. DC has positive and negative poles, which should not be confused during use. 2. Different DC currents have the same direction. The waveform is usually a sine curve. 3. DC is also called constant current, which is a type of DC where both the magnitude and direction remain unchanged. It was discovered by Edison. 4. DC can be obtained from batteries or by rectifying AC, making it more suitable for places where AC is inconvenient to use. 5. Devices in cars can only operate on DC. Some components, such as transistors and most integrated chips, are powered by DC.
