In the following circuit, the reading in the ammeter is
- A 25.1 mA
- B 22.5 mA
- C 21.5 mA
- D 21.25 mA
Answer & Solution
Correct Answer
(C) 21.5 mA
Step-by-step Solution
Detailed explanation
Reading of ammeter shows the current in the circuit.
Current is given by, \(I=V / R\)
I.(i) \(\frac{V-V_{\text {diode }}}{R}\)
For silicon diode, \(\mathrm{V}_{\text {diode }}=0.7 \mathrm{~V}\)
\(\therefore \quad \mathrm{I}=\frac{5-0.7}{200}=\frac{4.3}{200}=21.5 \mathrm{~mA}\)
