How will you conclude that the same potential difference (voltage) exists across three resistors connected in a parallel arrangement to a battery?

We will do the following activity to conclude that the same voltage exists across three resistors connected in parallel.

Connect the three resistors in parallel across the battery as shown in the figure below

● Now disconnect the voltmeter and connect it across R1.

● Note the reading of voltmeter. It is found to be V.

● Disconnect the voltmeter and connect it across R2.

● Again disconnect the voltmeter and connect it across R3. Note the reading of voltmeter. It is also found to be V.

Conclusion: When resistors are connected in parallel to each other, potential difference across each resistor is same.
