Frequently Asked Questions
What is a rectifier?
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. Read more..
What is a synchronous motor?
Unlike an asynchronous AC motor, a synchronous AC motor rotates at the same speed as the frequency of the AC power supply. In order to achieve this, the synchronous AC motor must be synchronized with the power supply using a feedback system. Read more..
How does AC differ from DC?
Direct current (DC) is an electric current that flows in one direction only. This means that the voltage of a DC signal does not change over time. DC signals are typically generated by batteries or solar cells.
Alternating current, on the other hand, is generated by power plants and flows through the power grid to homes and businesses. Read more..
What is a diode?
Diodes are semiconductor devices that allow current to flow in only one direction, making them useful for a variety of applications such as rectification, voltage regulation, and signal modulation. Read more..
