To verify Ohm's law for a test resistor, a student must convert a galvanometer into a voltmeter and an ammeter. The correct conversions are
Options:
Answer:
B
Solution:
A voltmeter needs a large total resistance, so a high resistance is connected in series with the galvanometer.
An ammeter needs a very small total resistance, so a low resistance (shunt) is connected in parallel with the galvanometer.
