1. ACTIVE DEVICES

 

• Active devices are different from passive devices such as resistors, capacitors and inductors. These devices are capable of changing their operational performance, may deliver power to the circuit, and can perform interesting mathematical functions.

 

• When doing most circuits problems we depends on idealized components. The following section will describe a number of components, thier models, and how to apply them in practical circuits.
