In circuits connected in parallel, the components are connected on different branches. Find out more with BBC Bitesize. For students between the ages of 11 and 14.

When two POL supplies connect in parallel, the output voltage difference between two modules can be as high as 1.5 V x 2% = 30 mV. So assuming a 5-mΩ interconnection impedance, the circulation ...

If you wanted, you can make a similar circuit with 10 or 20 bulbs. Just connect them all in a line so that the same current goes through each one. This is a series connection.
