In the circuits shown below, the readings of voltmeters and the ammeters will be: (a) V1 = V2 and i1 = i2 (b) V1 > V2 and i1 > i2 (c) V1 > V2 and i1 = i2 (d) V1 = V2 and i1 > i2

Answer: (a). Ideal voltmeters have infinite resistance, so no current flows through either voltmeter branch. Circuit 1: i₁ = 10/10 = 1 A, V₁ = 10 V. Circuit 2: the 10 Ω in series with V₂ carries no current, so it has no drop; V₂ = 10 V and i₂ = 1 A. So the answer is (a) V₁ = V₂ and i₁ = i₂.

Kirchhoff's Laws & Measuring Instruments

In the circuits shown below, the readings of voltmeters and the ammeters will be:

Show answer and solution

Answer: (a)

Ideal voltmeters have infinite resistance, so no current flows through either voltmeter branch.
Circuit 1: $i_1 = \dfrac{10}{10} = 1\text{ A}$ , $V_1 = 10\text{ V}$ .
Circuit 2: the $10\ \Omega$ in series with $V_2$ carries no current, so it has no drop; $V_2 = 10\text{ V}$ and $i_2 = 1\text{ A}$ .
So the answer is (a) $V_1 = V_2$ and $i_1 = i_2$ .
