Resistive forces in an ac circuit is?
Impedance
What means Impedance?
To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at least 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.
Why do not you use impedance in DC circuit?
Actually, its a matter of terminology... Impedance can be used in a DC circuit. We just call it resistance, however, transient analysis would imply a different notation. To be clear, impedance is normally used in AC circuits, and it is the electrical opposition to AC, taking into account not only voltage, but phase angle. In a DC circuit, impedance and resistance are the same thing, simply with a phase angle of zero.
What is electrical impedence?
Electrical impedance is the total opposition to current flow. It includes both a resistive, or DC component and a reactive, or frequency-dependant component. Impedance is the same as resistance if the applied voltage is DC. For AC voltage, the reactive components opposition to current flow changes with frequency, so impedance is typically specified at a particular frequency.
What is output impedence?
Newer heard the word "impedence". An output impedance is an AC resistance at the output of an electronic device.

Impedance
What does Ohms mean for an amp?
Every amplifier has a high input impedance and a low output impedance. These electrical impedances extends the concept of resistance to AC circuits and are measured in ohms. In electronics, especially audio and sound recording, a high impedance bridging, voltage bridging, or simply bridging connection is one which maximizes transfer of a voltage signal to the load.
Is a capacitor used to change an AC voltage to a lower or higher value?
Yes.... capacitors offer impedance to flow of ac current.. But since the value of impedance is inversly proportional to the frequency of source therefore the impedance offered generally is much lesser than in case of dc current
What is the opposition to the current flow?
resistance is the opposition to the flow of electric charge
Is impedance and resistance are different?
Resistance is a concept used for DC (direct currents) whereas impedance is the AC (alternating current) equivalent. Impedance is a more general term for resistance that also includes reactance.

WHAT STOPS a transformer windings FROM BEING A short circuit?
The transformer winding is a short circuit to DC. But for AC, the impedance of thecoiled winding and the magnetic coupling to another winding have the same effecton AC as resistance has in a DC circuit. That's why transformers don't work withDC, and are always operated with AC.AnswerIf you are querying why there are no short circuits between individual turns, it is because the windings are insulated not bare.
What is purpose of emmiter bypass capacitor in R-C coupled amplifier?
Emitter bypass capacitor is a capacitor which provide low impedance to AC and high impedance to DC . AC is shunt then only DC appears on RC and volage gain increses.
How does good regulation affect the short-circuit current of an ac generator?
I assume by good regulation you mean a minimal voltage drop internal to the generator. Minimizing this will inherently increase the short circuit current, because it requires minimizing the internal impedance of the generator.

Total opposition to current flow in an AC circuit with both resistance and reactance is called?
Impedance.
What is the relation between the ac voltage frequency and the capacitor impedance?
A capacitor impedance is equivalent to 1/jwC, where j = i = imaginary number, w = frequency, and C = capacitance in Farads.
