Let's consider the following diagram:

According to the Kirchhoff's voltage law, the algebraic sum of the voltages in a closed loop is zero.

From the above figure, it can be written that

$V_{1} + V_{2} - V_{3} = 0 \Rightarrow V_{1} + V_{2} = V_{3}$

Three voltmeters, all having different internal resistances are joined as shown in figure. When some…
