Electrical (A6)Pregunta 78 de 120
A voltmeter is connected how, relative to the component being tested?
a.In series with the load
b.Between the two battery posts only
c.After removing the fuse
d.In parallel (across) the component
Explicación
A voltmeter is connected in parallel across the component or connection to measure the voltage difference, since it has very high internal resistance. An ammeter, by contrast, connects in series. Connecting a voltmeter in series would give an incorrect reading.
