I have a coil. I want to accurately measure the amount of
energy/current that it uses when pulsed with one single square wave. I
know I can take a voltage and current measurement and multiply them
together to get a wattage. is that the only way? is there such as
thing as a wattmeter? that just simply tells me how much energy was
just used? I guess its a stupid question.
a side question - if I set my power supply to "constant current mode"
(say at .3A) and at 12V the most my coil can draw is 3.6 Watts correct?
so this would happen when I simply short the power supply with my coil.
