Let's say I have two separate 120V AC circuits, each with a triac (15A) that controls a heat element. The first circuit has a heat element that draws a maximum of 1000W. The second circuit heat element draws 2000W. In the first circuit, I leave the triac gate on at all times, and in the second circuit, the triac has a 50% duty cycle, so that the total power drawn is 1000W. If both of these circuits draw 1000W, will both triacs heat up at the same rate?
