  • The circuit shown in the figure contains two diodes each with a forward resistance of  <img alt="\mathrm{30 \Omega}" src="https://entrancecorner.oncodecogs.com/gif.latex?%5Cmathrm%7B30%20%5COm

The circuit shown in the figure contains two diodes each with a forward resistance of  \mathrm{30 \Omega} and with infinite backward resistance. If the battery is \mathrm{30 V}, the current through the \mathrm{50 \Omega} resistance (in ampere) is

Option: 1

Zero


Option: 2

0.01


Option: 3

0.02


Option: 4

0.03

In the circuit the upper diode \mathrm{D_1} is reverse biased and the lower diode \mathrm{D_2} is forward
biased. Thus there will be no current across upper diode junction. The effective circuit
will be as shown in figure.

Total resistance of circuit

\mathrm{ R=50+70+30=150 \Omega }

Current in circuit, \mathrm{ I=\frac{V}{R}=\frac{3}{150}=0.02 \mathrm{~A} }

Hence option 3 is correct.
