The diagram shows an electric
circuit. How many ammeters are there in the
circuit?

Okay, so in this diagram, we’ve
been shown a circuit that has lots of components in it. In fact, it has one, two, three,
four, five, six, seven, and eight components in it. So, that’s quite a large
number. But we’ve been asked to find how
many ammeters are in this circuit. So to answer this question, let’s
first start by recalling that the circuit symbol of an ammeter looks like a circle
with a capital A inside it. So looking back to our circuit, we
can see one of these ammeters, and here is another one. All the other components are not
ammeters because here we’ve got a cell, here’s a bulb, here is an open switch, here
is another bulb, a third bulb here, and a closed switch. Therefore, the answer to our
question is that there are two ammeters in the circuit.
