hiiiiiiiiiiiii
can you help me to answer this quistion
please
what should be PIV rating of the diode in the circuit?


if one of the diode in the rectifier is opens , what should be the possible output voltage


if one of the diode in the bridge rectifier shorts what are the possible consequences


discuss the effect of change in the value of filter capacitor used


what happens to output voltage of a rectifier if the capacitor becomes very leaky


if the primary winding of the transformer in the power supply , what will you observe in the rectified output



the dc output voltage of the filtered rectifier is less thae it should be . what could be the problem

ha ha ha, that looks like an assignment that you’ve been given and you want us to do it for you :stuck_out_tongue:
Questions are straightforward if you understand the concept behind any Power Supply unit… However, I’ll answer the one about the capacitor… Basically the capacitors job is to smooth the output, so if you change the value of the capacitor, then you either make the output smoother (better DC) or you might increase the ripple (worse DC) … Hope you do a bit of search over the net and inshallah you’ll get the rest of the answers.
