I have a full wave rectifier thyristor control circuit on a 10 Ohms resistor coil which produced the following results with 240V AC rms.
DC Current through coil (A) DC Voltage across Coil (V) AC Voltage across coil (V rms)
1.15 10.8 92.0
2.43 22.5...
if you measure the outputs A and B of a pulse width modulation circuit at zero duty cycle, it will measure equal voltage at A and B outputs with the same duty cycle with respect to ground resulting in 0V.
What will the output will look like please if measured between A and B outputs please.
I have a 7.5 kW motor with 110V, 40W anti condensation heater. But i have only 240 V supply for the heater, can I put a resistor in series with the heater to reduce the voltage please.
