Given an unfiltered half-wave rectifier circuit with an input ac voltage of 115 Vrms, a turns ratio of 4:1 (Npri:Nsec) and a load resistance of 50 Ω. Determine (a) peak value of the primary voltage, (b)peak value of the secondary voltage, (c) peak value of the load voltage, (d) dc load voltage, and (e) dc load current.
In a half-wave rectifier, the amplitude of the positive half of
the input waveform and the output waveform differ slightly in

+/-15V regulated supplies.
My Question:
What does it mean by a grounded-load? I am not really familiar
with this term.
