Solution
The correct option is B
Low resistance in parallel
The explanation for the correct option,
In the case of option B,
A galvanometer is a highly sensitive tool for measuring current. It is simple to transform into an ammeter and a voltmeter.
An ammeter is a device that measures the current flowing inside an electrical circuit. The ammeter must have a low resistance so that it does not affect the current flowing through it. To detect the circuit current, an ammeter is arranged in series.
By interconnecting a low resistance in parallel well with a galvanometer, an ammeter is created. Such low resistance is referred to as shunt resistance S. The screen has now been measured in amperes, and the ammeter range would be determined by the shunt equivalent resistance.
