Two lamps connected in series ... total current flowing out. The current is described as being conserved. Two lamps connected in parallel with an open switch and a cell The circuit diagram shows ...

To measure the current flowing through a component in a circuit, you must connect the ammeter in series with it. Remember, electric current is measured in amperes, or amps for short.

However, this is a great time to look at the difference between series and parallel circuits ... there is no longer a current. Here is the new diagram. Even though there is a break, the change ...
