    what would happen if one of the diodes in the rectifier was installed backwards? Include an explanation of the waveforms that would be observed and/or the voltages you would expect to measure across the load.

    Draw a rectifier with all the diodes the right way round.

    (a)Trace the currents for each 1/2 cycle,& determine the voltage across RL.
    As the load is resistive (no filtering),what can you assume about the waveshape & peak amplitude of this voltage?

    What is it's rms value?

    What is its average value?

    (b)
    Reverse one of the diodes,& again trace the currents,as before.
    What has now happened to the waveshape of the voltage across RL?

    What is its peak value?

    What is it's rms value?

    What is its average value?

    If you use this method you should be able to determine all the information wanted,plus cement a few concepts in your mind.
