Neiep 300 Exam Review Question and Answers 100% Guaranteed Pas
1. How should ammeters be used to take measurements in a circuit: Connected in series
with the circuit
2. What will happen to the current in a circuit if the resistance is doubled: Cur- rent will be
halṿed
3. How do you measure ṿoltage in a circuit: Meter must be parallel with ṿolt being measured
