Question

In the figures shown below

• A. In both Fig. (a) and Fig. (b) the diodes are forward based
• B. In both Fig. (a) and Fig. (b) the diodes are reverse biased
• C. In Fig- the diode is forward biased and in Fig. the diode is reverse biased
• D. In Fig, the diode is reverse biased and in Fig. it is forward biased

Answer 1

Answer: (C)

In Fig- the diode is forward biased and in Fig. the diode is reverse biased

Answer 2

The density of $d=\frac{M}{V}$ Error of density $d=\frac{\Delta M}{M}\times 100+\frac{\Delta V}{V}\times 100$ $=\frac{0.01}{22.42}\times 100+\frac{0.1}{4.7}\times 100$ $=0.044+2.127$ $=2.2$ (approximately)
