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.

In a series circuit, the total resistance across all of the components (the 'net resistance') increases as more components are added.

What analog designer hasn't had to derive a nonstandard resistor value by using series/parallel combinations of standard resistor values? In efforts to avoid a production trimpot tweak, we can use 0.1 ...
