AC Capacitance and Capacitive Reactance
https://www.electronics-lab.com/article/ac-capacitance-capacitive-reactance/
Introduction Such as for inductors, the electrical behavior of capacitors also depends on the nature of the source : DC or AC. We will see through this tutorial that in some way, the capacitor can be seen as the opposite of an inductor in terms of frequency functioning. Like for the resistors and inductors, we […]
AC Inductance and Inductive Reactance
https://www.electronics-lab.com/article/ac-inductance-inductive-reactance/
Introduction In the previous tutorial concerning AC resistance, we have seen that the behavior of a resistor is the same in DC or AC regime under normal frequencies. However, other basic electrical components such the inductor, strongly depends on the frequency of the AC signal. A presentation of the concept of inductance is given in […]
Complex Numbers and Phasors
https://www.electronics-lab.com/article/complex-numbers-phasors/
Introduction Complex numbers are an important mathematical tool that is widely used in many physics domains, including electronics. The concept might seem odd, but their manipulation is simple and their efficiency notable. In the first section, general concepts about the complex numbers are presented in order to get familiar with their representation. A second section […]
Frequency Response of Amplifiers
https://www.electronics-lab.com/article/frequency-response-amplifiers/
Introduction As such for any electronic circuit, the behavior of amplifiers is affected by the frequency of the signal on their input terminal. This characteristic is known as the frequency response. Frequency response is one of the most important property of amplifiers. In the frequency range that amplifiers have been designed for, they must deliver […]
