Then current through the load and voltage drop across the load are zero, and all the supply voltage appears between the anode and cathode of the SCR.

The reports should be returned to the students in the next lab period fol- lowing submission. The LTA should report any errors in the lab manual to the faculty coordina- tor. A Cathode Ray Oscilloscope (CRO) is an instrument generally used in a laboratory to display, measure and analyze various waveforms of electrical circuits. A cathode ray oscilloscope is a very fast X-Y plotters that can display an input signal versus time or other signal. CRO is a very versatile instrument in laboratory for measurement of voltage, current, frequency and phase angle of any electrical quantity. But before we go ahead with dis­cussion on measurement of electrical quantities with CRO, we should understand some basic oscilloscope patterns.
