"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.
resistance is the opposition to the flow of electric charge
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.
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
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.
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.
q is just a variable name. It represents different things in different equations around the world.
The property of a conductor that impedes the flow of charge is called resistance. It is measured in ohms and depends on factors like the material, dimensions, and temperature of the conductor.
The flow of electrical charge is called current. It is measured in units called amperes (A) and represents the rate of flow of electric charge in a circuit.
resistance is the opposition to the flow of electric charge
NO. Variable capacitory can store a small charge
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.
The variable for charge in coulombs is typically represented by the letter "Q".
A heraldic charge in the form of a ring is called an annulet. It represents strength and unity. It is often used in coats of arms to symbolize loyalty and continuity.

The flow of electrons in a circuit is called electric current. It is measured in amperes (A) and represents the rate at which electric charge flows through a circuit.

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.
