(B) Given the input voltage $V_{in} = 220 \sin(100 \pi t) \ V$.At time $t = 15 \ ms = 15 	imes 10^{-3} \ s$, the input voltage is:$V_{in} = 220 \sin(100 \pi 	imes 15 	imes 10^{-3})$$V_{in} = 220 \sin(1.5 \pi) = 220 \sin\left(\frac{3\pi}{2}ight)$$V_{in} = 220 	imes (-1) = -220 \ V$.In a center-tapped full-wave rectifier, when the potential at the top terminal of the secondary coil is negative with respect to the center tap, diode $D_1$ is reverse biased and diode $D_2$ is forward biased.

$A$ full-wave rectifier circuit with diodes $D_1$ and $D_2$ is shown in the figure. If the input supply voltage is $V_{in} = 220 \sin(100 \pi t) \ V$, then at $t = 15 \ ms$:
