Technician exam question T7D02
Subelement T7, PRACTICAL CIRCUITS· Group T7D
How is a voltmeter connected to a component to measure applied voltage?
- A.In series
- B.In parallel (correct answer)
- C.In quadrature
- D.In phase
WhyA voltmeter is connected in parallel with a component to measure applied voltage. A voltmeter measures the voltage across a component, so it's connected in parallel with that component, sharing its two connection points without breaking the circuit's current path, answer B. It isn't connected in series (A), and "quadrature" (C) and "in phase" (D) describe phase relationships between AC signals, not how a meter is wired into a circuit.
