Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is A low resistance in parallel.
Explanation:
We can convert a Galvanometer into an ammeter by connecting a low resistance in parallel.
- Electric current is defined as the rate of flow of charge or electron, so its direction is the flow of positive charge.
- SI unit of the electricity is Ampere(A) and it is a scalar quantity.
- Resistance is the opposition delivered by the conductor in which current flows through it.
- A device that is used to measure electric current in a circuit is called an ammeter. The resistance of an ideal ammeter is always Zero and is always connected in the circuit in series.
- A voltmeter is a device that is used to measure the potential difference between the two points in a circuit. The resistance of an ideal voltmeter is infinite.
- A galvanometer is a device that is used to detect and measure small electric currents in any circuit. It can measure current up to 10-6 Ampere.
- Now the interesting fact is:
We can convert a Galvanometer into an ammeter by connecting a shunt parallel to it.
We can also convert a Galvanometer into a voltmeter by connecting a very high resistance in its series
