what is firing angle?

## 2 Answers

### Answer :

Firing angle is the angle at which the sin angle is delaying to start the waveform.

### Answer :

Firing angle is time in electrical degrees from the instant the valve voltage is positive to the application of firing pulse to the valve (start of conduction). Also called delay angle.
