Bridge Rectifier Circuit

[Surjeetsinh Chauhan]

I am Trying to design a simple bridge rectifier on Breadboard by connecting negative of source to ground but when i connect Node 1 to 4 Channel Oscilloscope +ve pin with -ve pin GND , i get Half wave , but when i connect +ve pin to Node 1 and -ve pin to Node 2 i get same half wave at output and Input also becomes half wave how to solve this issue please help ??

Your input sinewave is grounded. Usually the input sinewave comes from a transformer winding without a ground. Then you can ground the negative output (Node 2 on your sketch) and get full wave rectified positive pulses from Node 1.

Thank you for your reply. i found this circuit on one website using Multisim , where ground is on -ve of input and no ground on other side after rectification .

my issue is with ground pin of Oscilloscope when i connect it to Node 2 my input is getting clipped.

Because your input has a ground and your oscilloscope also has a ground then half of the bridge rectifier is shorted.
