A-15. A multimeter (high resistance) is placed in series with the coil of the meter.
A-16. The current required for full-scale deflection, and the range of the voltage to be measured.
A-17. In parallel.
A-19. Ohms per volt.
A-20. Megohmmeter (megger).
A-21. 1. A source of dc potential. 2. One or more resistors (one of which is variable).
A-24. Shunts leakage current, which prevents false readings.
A-26. Friction clutches.
A-27. Fixed coils.
A-28. Size of spiral conducting.
A-29. The electrodynamometer-type meter can be used to measure both ac and dc currents.
