it is combined effect of resistance and inductance
That term to me is incorrect it should be capacitance impedance. Resistance is linear impedance. CAPACITANCE will follow a vector caused by the capacitor value.
The legal term for impedance is "hindrance" or "obstruction." It refers to any obstruction or barrier that hinders the fulfillment of a legal right or duty.
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.
Since impedance is the vector sum of resistanceand reactance, and since reactance is a function of frequency, impedance only really applies to a.c. circuits. You could argue that, in a d.c. circuit, impedance is equal to resistance, but the term really isn't normally used in d.c.
The term Impedance (Z) is used to quantify the opposition to current flow in a circuit.
Impedance is the complex form of resistance. Impedance takes into account capacitance and inductance in a circuit as well. Impedance can be represented as resistance as a function of frequency.See link.AnswerImpedance is not a 'complex form of resistance'. It is the vector sum of a circuit's resistance and reactance. In electrical engineering, 'resistance' has a very specific meaning, and cannot be used to denote 'opposition'.
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.
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.
In terms of electrical engineering, the term "bridging" refers to connecting a load to two amplifiers. This is done to increase the voltage. It can also refer to the use of an impedance with a low source to power an impedance with a larger load, again to maximise the voltage.

load 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.
