The diagram shows an electric
circuit. How many voltmeters are there in
the circuit?
Here, we are given a diagram of an
electric circuit with many different components, and we are asked to find out how
many voltmeters are present. To answer this question, we’ll need
to know the circuit symbol of a voltmeter. In a circuit diagram, like the one
we have here, a voltmeter appears this way. Anywhere we see this symbol in our
diagram, we know that a voltmeter is present.
Looking at our diagram, we count
one, two, three instances of this symbol. We know therefore the number of
voltmeters in this circuit. The answer is three voltmeters.
