How did you do Amps?

How did you display Amps? I know the math, I just cannot figure out how it works within the IoTaWatt calculator.


I divided power by voltage. Of course this only works when PF = 1.00. I was just doing that to get in the ballpark as I was doing my high-tech thing screwing in various wattage light bulbs to get the desired approximate current. I had a precision meter on the primary wire but because the CT was measuring eight turns the meter was only showing 1/8 of the test current. It was a quick and easy way to get in the zone.
