Question

A battery of emf $1.4$V and internal resistance $2\Omega$ is connected to a resistance of $100\Omega$ through an ammeter. The resistance of the ammeter is $1.33\Omega$. A voltmeter is connected across the $100\Omega$ resistance. If the current in the circuit is $0.02$A, what is the resistance of voltmeter? If the voltmeter reads $1.1$V, what is the error in the reading?

• A. $200\Omega ,-0.23$V
• B. $400\Omega ,+0.46$V
• C. $600\Omega ,-0.69$V
• D. $800\Omega ,+0.92$V
