Hello,
this might be a simple question for some of you, but I am stuck at this.
Imagine a simple circuit:
A 0.22 uF / 1000 V Capacitor is charged through a 1 k ohm Resistor and 1000 Volt 1 A Diode. The source voltage is 200 HZ AC Sine Wave with a peak to peak voltage of 400 Volts.
I want to use this circuit as a peak voltage detector.
At the moment of first charge, when the capacitor is completely empty, it is like a shortage to the circuit and theoretically the current is infinite, right?
How do I calculate the correct wattage for a 1 k Resistor?
Thanks
Tronoty
