Typical assortment of 70 resistors. The “trimpot” is the standard solution to the analog designer’s occasional need to fine-tune a resistance in a precision circuit.

Adding more components to a series circuit increases the total resistance in the circuit, so less current flows. The circuit on the left contains a lamp, a cell, a switch, and an ammeter. 4 A of ...

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.
