Question:

The current flowing through 10Ω resistor in the circuit shown in the figure is:

Options:

50 mA

20 mA

40 mA

80 mA

Correct Answer:

80 mA

Explanation:

In the given circuit, junction diode $D_1$ is forward biased and will conduct whereas junction diode $D_2$ is reverse biased and will not conduct. Therefore current through 10Ω resistor is

$I=\frac{2V}{10Ω+15Ω}=0.08A = 80 mA$
