Introduction - Basic Circuit Theory
Bourns® resistive products exist to help make electrical circuits work the way they were intended. Before you can know what Bourns product is right for the job, you need to have an understanding of the fundamental laws of electricity and the basic terms used in describing electrical circuits.
The main benefits of your successfully completing this module are that:
- you will be better able to understand your customer's needs
- you will feel more confident in talking with your customer
Bourns objective for this module is to provide you with basic information on how electricity works. If you already have this basic information, please consider this module as a "refresher".
When you have completed this module, you should be able to remember:
- how electricity works
- the definition of the terms electricity, conductor, insulator, voltage, volt, current, amp, resistor, Ω, series circuits, parallel circuits, power, watt, alternating current, direct current and frequency
In addition, you should also be able to:
- use Ohm's Law to calculate voltage, current, resistance, and power
