Z = SQR (R² + XL²)

Where:

Z = Impedance (ohm)
R = Resistance (ohm)
XL= Inductance Reactance (ohm)

What is the equivalent impedance of a resistor and capacitor in parallel?

The equivalent impedance of a resistor and capacitor in parallel is calculated using the formula Z 1 / (1/R 1/Xc), where Z is the total impedance, R is the resistance of the resistor, and Xc is the reactance of the capacitor. This formula takes into account the combined effects of resistance and capacitance in the circuit.


What is the total impedance of a circuit with a capacitor in parallel with a resistor?

An inductor has an inductive reactance of 64ohm's and a wire resistance of 36ohm's what is the impedance of the inductor?

Impedance is a vector sum using the formula Z = square root (XL2 + R2); where Z = impedance, XL = inductive reactance, and R = resistance. Therefor the formula for a circuit where XL = 64ohm's and R = 36ohm's is Z = square root(642 + 322); Z = 71.6ohms.


Which is better high input impedance or low input impedance and why?

That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.


How to distinguish between characteristic impedance and input impedance?

The characteristic impedance or surge impedance belongs to uniform transmission lines.In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.


Input impedance is greater than to load impedance?

In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance.
