Question

An ammeter, a voltmeter V and a resistance R are connected as shown. Ammeter reads 2 A . Voltmeter reading is 10 V. Then R is (A) 50 Ω  (B) > 5 Ω  (C) < 5 Ω  (D) dependent on resistance of voltmeter

Tardigrade Admin · Accepted Answer

Voltmeter reading, V = 10 V, Ammeter reading, I = 2 A V=I1R = 10 Here, I1 < 2A, · So R > 5 Ω This happens due to resistance of voltmeter.

Q. An ammeter, a voltmeter $V$ and a resistance $R$ are connected as shown. Ammeter reads $2 A$ . Voltmeter reading is $10 V$ . Then $R$ is

$50 Ω$

$> 5 Ω$

$< 5 Ω$

dependent on resistance of voltmeter

Voltmeter reading, $V = 10 V$ ,
Ammeter reading, $I = 2 A$
$V = I_{1} R = 10$ Here, $I_{1} < 2 A,$
· So $R > 5Ω$
This happens due to resistance of voltmeter.

Q. An ammeter, a voltmeter V and a resistance R are connected as shown. Ammeter reads 2A . Voltmeter reading is 10V. Then R is

50Ω

>5Ω

<5Ω
