1.Why is a shunt needed if we are going to use a D'Arsonval meter as an ammeter?

2. Two examples of an ammeter shunt used in an aircraft.

3.A shunt resistor should be placed in ________ with the D'Arsonval meter movement to creat a usable ammeter.

4.When we use an ammeter it should be placed in __________ with the load.

5.D'Arsonval voltmeter:

5.1.What would need to be added to a D'Arsonval meter movement if we are going to use it as part of a voltmeter?

5.2.Why?

5.3. How is it added (in parallel or series with the meter?)

5.4.A voltmeter is placed in _____________ with the load.

6.A D'Arsonval ohmmeter uses a(n) _________________________ which passes current through both a known and unknown resistor.

7.Match: Potentiometer, shunt, megger

A.Used to measure high resistance such as wire insulation

B.Most analog ohmmeters are this type

C.Used to measure very low resistances

8.Draw a 4-diode bridge rectifier.

9.When is this rectifier used?

10.What is the main difference between a D'Arsonval voltmeter/ammeter and an electrodynamometer watt meter?

11.What does the electrodynamometer watt meter measure?

12.The electrodynamometer volt meter uses the same principle as the watt meter, except both coils _____________________________________.
