To answer this question, we need more specific information about the resistors, such as their resistance values, and the voltage of the power supply. However, I can explain the general process of how to calculate the new reading on the ammeter when the resistors are connected in parallel.

1. First, we need to calculate the total resistance of the circuit when the resistors are connected in parallel. The formula for total resistance (Rt) in a parallel circuit is given by:

1 / Rt = 1 / R1 + 1 / R2

Where R1 and R2 are the resistance values of the two resistors.

2. Once we have the total resistance, we can calculate the total current in the circuit using Ohm's law. Ohm's law states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R). So:

I = V / Rt

Where V is the voltage of the power supply.

3. The reading on the ammeter when S is closed will be equal to the total current in the circuit, as calculated in step 2.

Remember, this is a general process. The actual calculations will depend on the specific values of the resistors and the power supply voltage.
