    I want to ask that why do we use Bridge rectifier instead of Single diode?? in short single diode can also covert the AC to DC. I want o update my knowledge with strong logic. please do help me to know about it.

    Thanks!

    there is less ripple with a four diode bridge, making it easier to filter.

    A single diode filters off the bottom half of the sine wave. A bridge rectifier flips the bottom half to the top hence more voltage and more current and less ripple.

    Draw a sine wave. Cover the bottom half with a piece of paper. What's showing is what you get with a single diode. Now cut the paper with the sine wave on it along the zero line and flip the bottom half to the top of the zero line. That's what you get with a bridge rectifier. Pretty simple, really.
