An ammeter is a device used to measure
AMagnetic flux around a coil
BPotential difference between two points
CResistance of a conductor wire
DElectric current in a circuit
Answer & Solution
Correct answer: D. Electric current in a circuit
1. The chapter mentions a galvanometer or ammeter to detect current.
2. An ammeter is calibrated to read current in amperes.
3. Voltage is measured by a voltmeter; resistance by an ohmmeter.
4. So option A is correct.
