Solution

Step 1: Construction of circuit
Connecting three resistances R₁, R₂, and R₃ in parallel combination across a battery with voltage V.
Adding a voltmeter in parallel combination and an ammeter in series.
Step 2: Circuit diagram
Step 3: Observation
Take the reading of the potential difference of R₁ and R₃, when R₂is absent.
Take the reading of the potential difference of R₂ and R₃, when R₁is absent.
Voltmeter reading is the same in each case. This shows that the potential difference is constant across three resistors connected in a parallel arrangement.
Therefore, the potential difference is the same in the case of parallel combination of resistors.
