How will you conclude that the same potential difference (voltage) exists across three resistors connected in a parallel arrangement to a battery?
• Take three resistors R1, R2, and R3 and connect them in parallel to make a circuit; as shown in figure.
• Use voltmeter to take reading of potential difference of three resistors in parallel combination.
• Now, remove the resistor R1 and take the reading of potential difference of remaining resistors’ combination.
• Then, remove the resistor R2 and take the reading of potential difference of remaining resistor.
Observation: Voltmeter reading was same in each case. This shows that the same potential difference exists across three resistors connected in a parallel arrangement.
