Solution

Q.
In the given circuit, the voltage across load resistance $(R_{L})$ is [2024]

1 8.75 V

2 9.00 V

3 8.50 V

4 14.00 V

Ans.
(1)

${(V_{B})}_{S i} = 0.7 V$

${(V_{B})}_{G e} = 0.3 V$

Voltage drop across both diodes $= 0.7 + 0.3 = 1 V$

So remaining 14 volts will drop across $R_{L} \Rightarrow$

$V_{L} = \frac{2.5}{(1.5 + 2.5)} \times 14 = \frac{2.5}{4} \times 14 volt = 8.75 volt$
