Frequently Asked Questions
How do rectifiers work?
Rectifiers work by allowing only half of the AC cycle to pass through them. During the positive half-cycle, the rectifier allows electrons to flow from the negative terminal to the positive terminal. 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..
What is Ohm’s Law used for?
Ohm’s law is used to calculate the current in a circuit.
For example, if you know the voltage and resistance of a circuit, you can use Ohm’s law to calculate the current. 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..
