What is the legal term for impedance?
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.
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.
Is it the impedance value same in AC and DC?
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.
What is the impedence?
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'.
What is the term for opposition to current flow within a circuit?
The term Impedance (Z) is used to quantify the opposition to current flow in a circuit.
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 does the term bridging mean in electrical engineering?
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.
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.
Is characteristics impedance of a filter is same as output or load impedance?
load impedance
What is ment by impidance?
Impedance is a measure of opposition to the flow of alternating current in a circuit. It consists of both resistance (due to the circuit elements) and reactance (due to the effects of capacitance and inductance). It is represented by the symbol Z and is measured in ohms.
Why the impedance of infinite bus bar is zero?
...because it is an infinite bus bar, meaning it can supply infinite current. By Ohm's law, since the voltage at the bus bar is fixed, to have infinite current, you must have a zero impedance.
