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.
