Question - A centre-tap full-wave rectifier is supplying to a load of one kilo-ohm. If the voltage across half the secondary winding of the input transformer is 220 sin ωt, calculate the following:
(i) the peak value of current
(ii) the average value of the current
(iii) the r.m.s. value of current
(iv) the ripple factor
(v) the efficiency of rectification
