This circuit and circuit diagram contain a cell and two ... the total current out of a junction. 5 A = 3 A + 2 A. If a second lamp is added in parallel, it also has the same potential difference ...

The one in this picture is called a 'series circuit'. The other is called a 'parallel circuit ... each LED requires a minimum of roughly 2.5 volts to emit light (some need a little less, others ...
