Dear Sir/Madam,
When I tried out the basic bridge rectifier experiment in the lab,I found that it was not possible to observe both the input and output wave forms of the bridge rectifier on the CRO screen together though the input and rectified output could be observed separately.
When both CRO channels were used,the output resembled that of a half wave rectifier.The behaviour was the same when the input was fed from a signal generator as well as from a transformer.(I tried using the extreme terminals of a centre tap transformer with the common terminal grounded but still the response was the same)
What could possibly be wrong Sir.Kindly help me.
