Question
What is rectification?
Solution
- Rectification is the process of converting alternating current into the direct current is called rectification.
- An alternating current voltage varies sinusoidally, which means that its value and direction change in one cycle.
- A rectifier turns this bidirectional voltage or current to a unidirectional voltage, which is then converted to a DC voltage. This is known as correction.
- Rectification is the process of converting an alternating current voltage to a direct current voltage.
