This is a series circuit.
We measure current using an ammeter.
An ammeter must be connected in series with other components in a circuit. This means we need to break into the circuit when we add an ammeter.
The current in a series circuit is the same at all places in the circuit.
We can write this current relationship as:
Look at the series circuit below - what is the reading at?
Position one: more than 0.1A, 0.1A or less than 0.1A
Position two: more than 0.1A, 0.1A or less than 0.1A
Position three: more than 0.1A, 0.1A or less than 0.1A
Position 1 = 0.1A
Position 2 = 0.1A
Position 3 = 0.1A
Remember that the charge moves all the way around the circuit.
