A) high resistance in parallel
B) high resistance in series
C) low resistance in series
D) low resistance in parallel
Correct Answer: B
Solution :
A voltmeter is an instrument used for measuring the voltage between two points in an electric circuit. The voltage can be voltmeter measured by allowing it to pass a current through a resistance, therefore, a voltmeter can be seen as a very high resistance ammeter.
In order to increase the range of voltmeter, the instrument should draw a minimum of electric current to operate. This is achieved by using a sensitive ammeter or microammeter in series with a high resistance.
