@All.

Here, all are giving just no of node pairs which actually give branch voltages.
Here asking for node power voltage for kcl.

So, anyone, please clarify this clearly.

Formula n(n-1)/2, n = number of nodes.

45 is the correct answer.

Your explanation is correct @Ashish.

According to me, the answer is 45. Ref : J.B Gupta.

Is there any reference? Please explain this.

The first point could be any one of the 10 nodes. The second point could be any one of the 9 remaining nodes.

So there are (10 x 9) = 90 ways to connect my voltmeter.

But for each one, there's another one that's just the same two points. But with opposite polarity.

So there are 90/2 = 45 distinct different pairs of nodes.
