The phase angle of gate signal in TRIAC can be shifted by using_____________?
Correct answer: D. Only (a) and (b)
- A. A capacitor
- B. A variable resistor
- C. An inductor
- D. Only (a) and (b)
Explanation
A TRIAC firing circuit commonly uses an RC network, where the capacitor charging time and variable resistance determine the gate-pulse delay or phase angle. Hence both a capacitor and a variable resistor can provide phase control.
