Bob F Posted February 17, 2009 Report Share Posted February 17, 2009 Technician A says a voltmeter is connected in series to measure voltage. Technician B says it is connected in parallel. Who is correct? Technician A only. Technician B only. Both Technicians A and B. Neither Technicians A nor B. Quote Link to comment Share on other sites More sharing options...
Bob F Posted February 18, 2009 Author Report Share Posted February 18, 2009 OK, nearly half of you struggled with this one, which is ok because it helps me to refocus the questions. The correct answer is Technician B only. A voltmeter is always used in parallel (or across the thing you are measuring). For example. when you measure the voltage across the terminals of a battery you are placing the meter in parallel with the battery. I probably need to define what parallel and series circuits mean, so I will try to do that in the next posts. BF Quote Link to comment Share on other sites More sharing options...
Bob F Posted February 20, 2009 Author Report Share Posted February 20, 2009 A VOLTMETER measures the voltage potential across or parallel to the circuit. The Voltmeter measures the amount of electrical pressure difference between two points being measured. Voltage can exist between two points without electron flow.
