Question

The given circuit has two ideal diodes connected as shown in the figure below. The current flowing through the resistance $R_1$ will be

• A. 2.5 A
• B. 10.0 A
• C. 1.43 A
• D. 3.13 A

Answer 1

Answer: (A)

2.5 A

Answer 2

The diode $D_1$ will be be in reverse bias, so it will block the current and diode $D_2$ will be in forward bias, so it will pass the current . $i = \frac{10}{2+2} = 2.5 A$
