(a)For the CRO display of a pulse waveform, the time/em is on 10 ms/cm and vol/em switch is on 0.3 V/em. the width of half cycle is 3.5 em and the peak to peak height of the pulse is 2.4 cm. Determine a) the periodic time b) the frequency and e) the magnitude of the pulse voltage. 5 |(i) A 230 V ampere-hour type meter is connected to a 230 V DC supply. If the meter completes 220 revolutions in 15 mimutes when carrying 15A, cakulate: () The kWh registered by the meter, and (i) The percentage error of the meter above or below the original calibration. The timing constant of the meter is 20 A-s'revolution.
