Weird. I have both simulated (shown in picture) and practical circuit built. Simulation works as expected.
On the practical circuit, the output of the full-wave bridge rectifier gives the result similar to simulation. But after implementing a voltage divider (in order to scale-down the rectifier's output voltage of 7.3V to 4V for microcontroller to read) at the rectifier's output, the output of the voltage divider (as well as the output of the rectifier) gives a value near-zero (millivolts range). Any idea what happen to my practical circuit?
(As you can see, the simulated circuit is working as expected, 7.3V can be scaled-down to 4V. But not sure what's the reason of the practical circuit being brought down to approx. 0V after implementing the voltage divider...)
(Transformer: Scales down 230Vrms to 6Vrms; FW Bridge Rectifier: Convert sine AC to pulsating DC; Voltage Divider: Further scale-down voltage to 4V)
