Two ideal diodes are connected in the network as shown in figure. The equivalent resistance between A and B is ______

Ω

Answer: 25

Solution

In the given circuit, the diode in the upper branch is forward biased (conducts) while the diode in the lower branch is reverse biased (does not conduct).

Since only the upper branch conducts, the equivalent resistance is simply the sum of resistances in that branch:

R_{eq} = 10 Ω + 15 Ω = 25 Ω
