Hi guys,
For a science experiment I've got to measure the power consumption of my circuit of a 100W incandescent light bulb connected to the mains AC, with a dimmer switch to vary its brightness. I was planning on just using one of those plug-in energy monitors with a digital display but I've heard that when there is a dimmer in the circuit (triac) this would make the readings of these plug-in energy monitors completely wrong - errors up to 50% - is this true? If so how else can I easily measure the power consumption of such a circuit?
Thanks
