Hi all,
I recently designed a passive second order butterworth filter for 50Hz central frequency to be used on 240 mains voltage. The idea is to step down the voltage from 240 to 5V using a resistor divider. I made the circuit but when I connected it, the resistor divider just blew up. The rest of the circuit is fine.
I carried out simulation on proteus before hand to see if there is a large current flowing through any part but the current is around 360mA.
Please help me out. I cant figure out why the resistors are blowing up. Both resistors are rated at 1W.
Regards,
