resistance is the opposition to the flow of electric charge
Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.
As the source impedance is equal to load impedance, it is assumed that both the resistances are in series. This distributes the whole voltage equally between both the impedance. Hence the PD across external resistance will be 1V.
The impedance of a circuit having an inductance and a capacitance in parallel at the frequency at which this impedance has a maximum value. Also known as rejector impedance.
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.
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.
This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.
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'.
An impedance triangle has resistance (always positive) in the x axis and reactance (at a right angle to resistance) in the y axis. The line that completes this triangle (the hypotenuse) is the absolute value of the impedance.
Impedance, resistance, and reactance.
resistance is the opposition to the flow of electric charge
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.
Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.
Impedance is measured in Ohms defined as total resistance to current (Amps) flow
Impedance in an AC circuit is like resistance. In fact, impedance is measured in ohms, just like resistance. Impedance takes into account the fact that current and voltage are often not in phase with each other due to capacitive and inductive reactance.
As the source impedance is equal to load impedance, it is assumed that both the resistances are in series. This distributes the whole voltage equally between both the impedance. Hence the PD across external resistance will be 1V.
Bulk resistance is the ohmic resistance of the semiconductor material. The natural resistance of a "P" type or "N" type semiconductor material.
