Question
An ammeter of range $5 \mathrm{~A}$ is to be converted into an voltmer of range $10 \mathrm{~V}$. If the resistance of ammeter be $0.1$, then what resistance should be connected in series with it ?(A) $4.9 \Omega$(B) $2.1 \Omega$(C) $1.1 \Omega$(D) $1.9 \Omega$
Step 1
Step 1: We know that the resistance to be connected in series can be calculated using the formula $R = \frac{V}{I} - G$, where $V$ is the voltage, $I$ is the current, and $G$ is the resistance of the ammeter. Show more…

An ammeter of resistance $0.2 \Omega$ reading upto $10 \mathrm{~mA}$ is to be used to read upto $1 \mathrm{~V}$ potential difference. We have to connect a. $99.8 \Omega$ resistance in series b $99.8 \Omega$ resistance in parallel c. $0.1 \Omega$ resistance in parallel d. $0.1 \Omega$ resistance in series
An ammeter reads up to $1 \mathrm{~A}$. Its internal resistance is $0.81 \Omega$. To increase the range to $10 \mathrm{~A}$, the value of the required shunt is (A) $0.03 \Omega$ (B) $0.3 \Omega$ (C) $0.9 \Omega$ (D) $0.09 \Omega$
When an ammeter of negligible internal resistance is inserted in series with circuit it reads $1 \mathrm{~A}$. When the voltmeter of very large resistance is connected across $R_{1}$ it reads $3 \mathrm{~V}$. But when the points $A$ and $B$ are short circuited by a conducting wire then the voltmeter measures $10.5 \mathrm{~V}$ across the battery. The internal resistance of the battery is equal to: (a) $\frac{3}{7} \Omega$ (b) $5 \Omega$ (c) $3 \Omega$ (d) none of these
