"I" represents the current which is the flow of electric charge. Impedance is the measure of the opposition to the flow of current at a given voltage usually in a.c. circuits.

What is the opposition to the current flow?

resistance is the opposition to the flow of electric charge


The opposition to the flow of electrons through a conductor?

In the simplest case, that would be resistance - but there is also another type of opposition (only relevant for AC) called reactance. The combined effect of resistance and reactance is called impedance.


What is chargeback method?

It is a technique that uses accounting entries to allocate the indirect costs of running the IT department. it has 4 methods: # no charge method # fixed charge method # variable charge method based on resource usage # variable charge method based on volume


What is spectral solar impedance?

No such thing. Impedance is a property of alternating currents; even assuming that this applies to photons, you don't have the alternating...flow. That is, unless you're going to toss in dark energy as an opposite charge or something... that's beyond what I have on tap, though.


What will be the impedance of a C-R circuit consisting of a resistance of 20ohm and capacitance 2microfarad when it is connected to direct current?

In a direct current (DC) circuit, a capacitor will eventually charge up and act as an open circuit, meaning it will not allow current to flow after reaching full charge. As a result, the impedance of a resistor-capacitor (C-R) circuit under DC conditions is simply the resistance value. Therefore, the impedance of the given C-R circuit with a resistance of 20 ohms and a capacitance of 2 microfarads is 20 ohms.

What is called the unit of electric current?

The unit of electric current is called the ampere, which is symbolized as "A". It represents the rate of flow of electric charge or the amount of charge passing through a point in a circuit per unit time.
