What system regulates the flow of electricity in a device?
The system that regulates the flow of electricity in a device is the power supply or voltage regulator. These components ensure that the appropriate voltage and current are provided to various parts of the device, maintaining stable operation. They convert AC (alternating current) from mains electricity to DC (direct current) used by most electronic devices. Proper regulation is crucial as fluctuations in power supply can lead to device failure or damage, highlighting the importance of reliable power management.
