NEETPhysicsCurrent ElectricityMCQ+4 / −1
In the circuits shown below, the readings of voltmeters and the ammeters will be : NEET 2019 Physics - Current Electricity Question 40 English
  1. A
    V1 = V2 and i1 = i2
  2. B
    V1 > V2 and i1 > i2
  3. C
    V1 > V2 and i1 = i2
  4. D
    V1 = V2 and i1 > i2
View written solutionFree

Correct answer: A

Resistance for ideal voltmeter = ∞\infty ∞

Resistance for ideal ammeter = 0

For 1st circuit,

V1 = i1 ×\times× 10 = 1010×10{{10} \over {10}} \times 101010​×10 = 10 volt

For 2nd circuit,

10 Ω\Omega Ω is in series with ideal voltmeter. Therefore it will not affect the circuit.

So, V2 = i2 ×\times× 10 = 1010×10{{10} \over {10}} \times 101010​×10 = 10 volt

∴\therefore∴ V1 = V2

Hence, i1 = i2 = 10 V10 Ω{{10\,V} \over {10\,\Omega }}10Ω10V​ = 1 A
