Step 1: In this circuit, the diodes act as ideal diodes, which means they conduct when forward-biased and do not conduct when reverse-biased.
Step 2: Since the diodes are in forward bias, they behave as short circuits, and the total resistance in the circuit is the sum of the resistors in series, i.e.,
\( R_{\text{total}} = 10 \, \Omega + 20 \, \Omega = 30 \, \Omega. \)
Step 3: Using Ohm's law, \( V = IR \), the current supplied by the cell is:
\[ I = \frac{V}{R} = \frac{2 \, \text{V}}{30 \, \Omega} = 0.0667 \, \text{A} \approx 0.2 \, \text{A}. \]
Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): In an insulated container, a gas is adiabatically shrunk to half of its initial volume. The temperature of the gas decreases.
Reason (R): Free expansion of an ideal gas is an irreversible and an adiabatic process.
In the light of the above statements, choose the correct answer from the options given below:
