How is an ammeter connected in a circuit?
Series connect it within the line of the circuit for which you are interested in measuring the current flow. More detail Since we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow. One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
Why must you make current flow through the meter in order to measure it?
You must make current flow through anything in order for the effect of the current to be "noticed". Without current flow, you can have no work, and you can have no effect. In the case of the ammeter, there is a large shunt resistance across the meter. most of the current shunts through that resistance, but a very small part goes through the meter, which registers the current flow and indicates a proportional flow that is calibrated to the ratio of the meter's resistance versus the shunt resistance.
