Given circuit:
The and resistors are connected in parallel.
Step 1: Calculating the Equivalent Resistance
The equivalent resistance of the parallel combination is given by:
Calculating:
Step 2: Current Division in Parallel Resistors
Let be the current through the resistor and be the current through the resistor. By the current division rule:
Thus, .
Step 3: Calculating the Power Dissipated
The power dissipated in a resistor is given by:
The ratio of the power dissipated in the resistor to the resistor is:
Substituting the values:
Therefore, the ratio of heat dissipated per second through the and resistors is .
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:
