Question

An arrangement of an ideal diode and resistances are shown to make a circuit. The current drawn from the battery of 8 V is (1) 3 A (2) 2 A (3) 1 A (4) 4A​

Answer 1

Answer:-

(2) 2 A

Explaination:-

In circuit, D2 is forward biased and D1 is reverse biased. The current through D1 is zero. As diode D2 is ideal, its resistance is zero. The equivalent circuit of the given arrangement is shown in Fig.

The current drawn from battery.
