Vedclass · Answer

(D) In the positive half cycle of the input $V(t)$, diode $D_1$ is forward-biased and $D_2$ is reverse-biased. The current flows through $R$ and $R_1$. The output voltage across $R$ is determined by the voltage divider rule: $V_{AB} = V(t) \cdot \frac{R}{R + R_1}$.In the negative half cycle of the input $V(t)$, diode $D_2$ is forward-biased and $D_1$ is reverse-biased. The current flows through $R$ and $R_2$. The output voltage across $R$ is $V_{AB} = V(t) \cdot \frac{R}{R + R_2}$.Since the current flows in opposite directions through $R$ during the positive and negative half cycles, the output is not rectified.Because the resistances $R_1 = 100 \ \Omega$ and $R_2 = 150 \ \Omega$ are different, the voltage division ratios are different for the two half cycles.Therefore, the peak values of the voltage $V_{AB}(t)$ during the positive and negative half cycles will be different.

$A$. $Pa \cdot s$	$(i)$ $[L^2 \ T^{-2} \ K^{-1}]$
$B$. $N \cdot m \cdot K^{-1}$	$(ii)$ $[M \ L \ T^{-3} \ K^{-1}]$
$C$. $J \cdot kg^{-1} \cdot K^{-1}$	$(iii)$ $[M \ L^{-1} \ T^{-1}]$
$D$. $W \cdot m^{-1} \cdot K^{-1}$	$(iv)$ $[M \ L^2 \ T^{-2} \ K^{-1}]$

In the circuit given below, $V(t)$ is the sinusoidal voltage source. The voltage drop $V_{AB}(t)$ across the resistance $R$ is:
