In AC, impedance (Z) takes on real and imaginary components, and so do voltage (V) and current (I). Re(Z) is affected the DC resistance. Im(Z) is determined by the capacitive and inductive components of the circuit.

State three things which can affect the voltage in a circuit?
Ohms Law says that Voltage = Current * Ohms, so the twothings that can affect the voltage in a circuit are Current and Ohms. If have a non resistive impedance, i.e. a capacitor or inductor forming a reactance, then frequency can also affect the voltage but, mathematicaly, reactance is a frequency domain form of impedance, so my answer stands - Current and Ohms.
In a two stage amplifier does the input impedance of the second stage affect the voltage gain of the first stage?
as i understand this impedance is something that impedes, or adds resistance or something like that. ( There are impedance bonds on the railroad to divide the track up into sections for signal purposes) by words, you see the connection with impede and impediment. the impedance, like resistance, would have to be a factor to be reckoned with. I am only familiar with Impedance bonds-they are laid horizontally under the track structure, and are part of the signal system.
What is analog audio 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.
What means Impedance?

What is input and output impedance?
To get all the 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 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.
What is the electrical impedance of air?
Electical impedance of air is just under 377 Ohms. It depends on humidity and other factors. Dry air is close to free space. Scroll down to related links and look at "Characteristic impedance of free space ".
What factors affect reliability?

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.
What are non living factors that affect organism survival called?
Non living factors that affect organism survival are called abiotic factors. Living factors that affect organism survival are called biotic factors.
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. 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.
What are the factors which affect rate of diffusion?
the factors which affect rate of diffusion is the factors that mixing one substance to another.
What are the factors that affect the difference between the computed values and measured values?
-- rounding errors in computation -- non-ideal components, such as diodes with finite reverse resistance, inductors with resistance, power supplies with non-zero internal impedance, wire with inductance, etc.
What factors affect the globalization of an business?
Various factors can affect the globalization of a business. For example, cultural factors may affect how viable a product is in a certain location.
