The Essentials of Electronic Technology
Electronic technology is the branch of electrical engineering and physics that deals with the emission, behavior and effects of electrons. Electronic devices, in contrast, use electronics to create and manipulate signals and information. These systems can be used in a variety of applications, such as computers and mobile phones. This branch of engineering is essential for any company that wants to stay competitive.
Impedance
Impedance is a quantity that describes the amount of resistance that an electrical current face. When both the voltage and current are constant, the impedance is zero. However, when the voltage is varying, the impedance is never zero. In other words, when alternating current is present, the impedance is always greater than zero.
There are many conditions that can affect an impedance measurement, including stray capacitance and probe capacitance. Another issue that affects impedance measurement is the presence of DC bias. This is caused by the …
