JEE MAIN - Physics (2006 - No. 2)
The circuit has two oppositively connected ideal diodes in parallel. What is the current following in the circuit?
$$1.71$$ $$A$$
$$2.00$$ $$A$$
$$2.31$$ $$A$$
$$1.33$$ $$A$$
Explanation
$${D_2}$$ is forward biased whereas $${D_1}$$ is reversed biased.
So effective resistance of the circuit
$$R = 4 + 2 = 6\Omega $$
$$\therefore$$ $$i = {{12} \over 6} = 2\,A$$
