What is a freewheeling diode?
Understand the Problem
The question is asking for an explanation of what a freewheeling diode is, which is a component used in electronic circuits, particularly in the context of inductive loads. We are likely looking to provide information on its function and applications.
Answer
A freewheeling diode eliminates voltage spikes across an inductor when the power is turned off, protecting the circuit.
A freewheeling diode, also known as a flyback diode, is connected across an inductor to eliminate sudden voltage spikes caused by the inductive load when the power is turned off, protecting the circuit.
Answer for screen readers
A freewheeling diode, also known as a flyback diode, is connected across an inductor to eliminate sudden voltage spikes caused by the inductive load when the power is turned off, protecting the circuit.
More Information
The freewheeling diode is essential in circuits with inductive loads, such as relays and motors, where abrupt changes in current can cause damaging voltage spikes.
Tips
A common mistake is not correctly orienting the diode. The cathode should be connected to the positive side of the power supply.
