Full-wave rectifier with filter capacitor

It simulates it but not really. If you have 12V from the transformer then you'll have around 10.8V after the bridge rectifier depending whether you've used germanium or silicon diode because they have different voltage drop (around 0.3V for Germanium and 0.5-0.6V for Silicon) 2x because two diodes are always operational in a bridge rectifier. Now after the capacitor you'll have the 10.8x1.41=15.2V. 1.41 being a derivative the peak voltage formula. Now 15.2V will easily knee under a load especially with a 170mA transformer but thats not the point. The point is that even if you remove the load in your circuit EC still neglects the peak voltage and shows around 10.4V output.
