The TRIAC based AC voltage controller operates in phase control mode. The regulator is used to control heat of a welding coil. The supply voltage is 230V, 50HZ and heating element has a resistance of 200. If the TRIAC is fired at an angle of 60°, compute the rms value of the output voltage, rms value of the output current and power delivered to the load. If the firing angle for the TRIAC is delayed further by 50° ,what will be the new rms output voltage, rms value of the output current and power absorbed by the same load?
