10V
✓5. a. If a 10V full scale voltmeter is constructed from a 1 mA, 50 ohm d'Arsonval meter
movement, what will it read when connected as shown below?
b. Using the same meter movement as above, design an ammeter which will read full scale
when 100 mA is passing through it. Show the circuit diagram of this ammeter and specify all the
resistance values.
c. How would ou change your design so that the ammeter reads 10 mA full scale?
6. Draw the Wheatstone bridge circuit diagram and explain how it can be used to measure an
unknown resistance.
