Investigating resistance in circuits

Loading...

Description

Having developed our knowledge of electricity over the past few videos, in this practical activity clip, we’ll be examining some of the factors which affect the resistance of a circuit.  In particular, we’ll be looking at experimentally investigating how the resistance of a piece of wire depends on its length, and how the way in which resistors are connected affects their total resistance.

Key Words
