Voltmeter Readings in the Circuit
In the given circuit, three voltmeters with different resistances are connected in series. The potential difference across the voltmeters is denoted as v1, v2, and v3. We need to determine the reading on voltmeter v2.

Determining the Voltmeter Readings
To find the readings on the voltmeters, we need to consider the total resistance in the circuit and the potential difference applied across points A and B.

1. Total Resistance in the Circuit
When resistors are connected in series, their resistances add up to give the total resistance. Similarly, the total resistance of the circuit can be calculated by summing the resistances of the voltmeters. Let the resistances of voltmeter v1, v2, and v3 be R1, R2, and R3, respectively. Therefore, the total resistance (RT) is given by:
RT = R1 + R2 + R3

2. Potential Difference Applied
The potential difference applied across points A and B is denoted as VAB. This potential difference is shared across the resistors in the circuit. Therefore, the potential difference across each voltmeter can be calculated using Ohm's Law:
V1 = (R1 / RT) * VAB
V2 = (R2 / RT) * VAB
V3 = (R3 / RT) * VAB

3. Calculating the Reading on Voltmeter v2
To determine the reading on voltmeter v2, we substitute the values of V1 and V3 into the equation for V2:
V2 = (R2 / RT) * VAB

Explanation
The reading on voltmeter v2 depends on the ratio of its resistance (R2) to the total resistance in the circuit (RT) and the potential difference applied across points A and B (VAB). The reading will be higher if the resistance of voltmeter v2 is higher compared to the other voltmeters (R1 and R3) or if the potential difference applied across the circuit is higher.

It is important to note that the voltmeter readings are a measure of the potential difference across each voltmeter, not the potential difference across the entire circuit. Therefore, the readings on the voltmeters can be different even when they are connected in series.

In conclusion, to determine the reading on voltmeter v2, we need to know the resistances of all three voltmeters, the total resistance in the circuit, and the potential difference applied across points A and B.
