Concept:
- Electroscope:
- It is an early scientific instrument used to detect the presence of an electric charge on a body.
- The first electroscope was a pivoted needle electroscope invented in the year 1600 by British Physicist William Gilbert.
- It measures the charge that is dependent on the Coulomb electrostatic force that triggers the movement of the test charge.
Explanation:
- Seismograph:
- It is an instrument that is used to detect and record earthquakes. generally, it consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not.
- Ammeter:
- This is a meter that is used for measuring electric current. Current is the flow of electrons whose unit is ampere.
- Hence the instrument which measures the flow of current in ampere is called as Ampere meter or ammeter.
- the ideal ammeter has zero internal resistance.
- Voltmeter:
- It is an instrument used for measuring the electric potential difference between two points in an electric circuit that is connected in parallel.
- It usually has high resistance so that it takes negligible current from the circuit.
- An electroscope is a correct answer.
