Kirchhoff's Laws & Measuring Instruments

Three voltmeters, all having different internal resistances are joined as shown in figure. When some potential difference is applied across $A$ and $B$ , their readings are $V_1, V_2$ and $V_3$ . Choose the correct option.

Show answer and solution

Answer: (c)

$V_1$ and $V_2$ are in series, and that pair is in parallel with $V_3$ across A and B.
Series: $V_{AB} = V_1 + V_2$ . Parallel: $V_{AB} = V_3$ .
So the answer is (c) $V_1 + V_2 = V_3$ .
