JEE MAIN - Physics (2002 - No. 51)
If an ammeter is to be used in place of a voltmeter, then we must connect with the ammeter a
low resistance in parallel
high resistance in parallel
high resistance in series
low resistance in series
คำอธิบาย
KEY CONCEPT : To convert a galvanometer into a voltmeter we connect a high resistance in series with the galvanometer.
The same procedure needs to be done if ammeter is to be used as a voltmeter.
