Impedance and Energy Storage Batteries

Hi All, I understand that the impedance of free space, according to the formula E/H, is 377 ohms. I understand that if the impedance is high, a given electric field is associated …

The impedance of a load (a combination of components) in an AC current is a complex number. Impedance depends on frequency (except for pure resistances).

I could see that capacitor impedance is mostly negative. Does the negative sign has any significant meaning? Also why do people convert impedance to admittance for circuit …

I was researching what the total electrical resistance of the human body was and got some quite far ranging values. It seems to range from 1, OOO to 1OO,OOO...

I don''t fully understand how to work out the impedance from the given equation (5j-5)x (11j-11)/ (5j-5)+ (11j-11). Any help would be greatly appreciated...

So I''ve never gotten a straight answer as to how you calculate the resistance of a coil (or cap for that matter). I hesitate to use the term "impedance" because I''ve been told too …

How Does Increasing Frequency Affect Current, Voltage, and Impedance (Z)? hidemi Apr 30, 2021 Current Frequency Voltage

Homework Statement I come across the impedance for an inductor an capacitor combined is Z = XL - XC, for a resistor and capacitor in series is Z = sqrt(R^2 + XC^2) and …

Why is the coaxial cable impedance independent of it''s length? I am considering the model shown in the attached picture. Since the resistance, capacitance...

Although there are many types of operational amplifiers, different amplifier circuits are suitable for interfacing with different types of sensors, but most complex amplifiers are built …
