Which description matches each instrument?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Voltmeter - b, Ammeter - a, Galvanometer - d, Ohmmeter - c.
The correct matches are:
Voltmeter - b (A device that measures voltage)
Ammeter - a (A device that measures the magnitude of electric current)
Galvanometer - d (A device that measures the direction and magnitude of current)
Ohmmeter - c (A device that measures resistance)
