Much appreciated Gneil,
V/I = R
230/0.43 = 534.884,
Calculate I for new Voltage:
V/R = I
206/534.884 = 0.386
Power Dissipated = 206 * 0.386 = 79.5 W
Is this correct?
Homework Statement
A triac is used in a dimmer switch to control a 100W light bulb. If the firing angle is set for α=∏/3 estimate the power dissipated in the bulb Rated at 100W and the voltage source 230V @ 50Hz.
