Question $2$

$($a$)$ For the rectifier shown in Fig. $2-1,$ determine: the diode voltage $=0\mathrm{.}7$V

i$.$ The diode conduction angle in degrees.

ii$.$ The load DC and RMS voltages.

iii. The load power dissipation.

Note. $\backslash$int sin$^(2)(\backslash$theta $)$d$\backslash$theta $=(\backslash$theta $)/(7)-($sin$(2\backslash$theta $))/(4).$

$($b$)$ For the limiter circuit of Fig. $2-2,$ assuming each diode has a $0\mathrm{.}7$ V turn$-$on voltage,

i$.$ Explain the operation of the circuit including sketching the input and output voltage

waveforms on the same plot.

ii$.$ Calculate the instantaneous power dissipated by the resistor if the magnitude of the output

voltage is at its maximum value.
