ABSTRACT

Yet, despite being probably the best-known ‘law’ in electrical engineering, it remains the most misinterpreted and least understood by electricians and technologists!

Ohm’s experiments were very simple by today’s standards, but must have been very diffi cult to perform in the early nineteenth century because, of course,

On completion of this chapter, you should be able to

1 state Ohm’s Law of Constant Proportionality. 2 describe the circumstances under which Ohm’s

Law applies. 3 describe the difference between ‘linear’ (‘ohmic’)

and ‘non-linear’ (‘non-ohmic’) materials and circuit components.
