An ammeter can be converted into a voltmeter by connecting
Open in App
Solution
The correct option is C a high resistance in series
An ammeter is a galvanometer with a small resistance(shunt) in parallel with it. The ammeter is connected in series in the circuit, because of this almost maximum current passes through the ammeter and current in circuit(almost same for series combination) remain invarient. While the voltmeter is connected in parallel across the component whose voltage is to be measured in the circuit. Hence, current will now divide along two paths. to avoid passage of maximum current through voltmeter its resistance should be very high(nearly infinity).
Hence, to convert an ammeter into voltmeter a large resistance is connected in series so the circuitry of voltmeter will not draw the most of the current from the circuit and will read the accurate voltage.
