Question 531: Current Electricity

Question

In the following circuit, the reading in the ammeter is

Accepted Answer

Reading of ammeter shows the current in the circuit.
Current is given by, $\mathrm{I}=\mathrm{V} / \mathrm{R}$
I. (i) $\frac{\mathrm{V}-\mathrm{V}_{	ext {diode }}}{\mathrm{R}}$
For silicon diode, $\mathrm{V}_{	ext {diode }}=0.7 \mathrm{~V}$
$$	herefore \quad I=\frac{5-0.7}{200}=\frac{4.3}{200}=21.5 \mathrm{~mA}$$
