What are the factors effect on the value of impedance when connect inductor and resistor in series?

Impedance (expressed in ohms) is the vector sum of a load's resistance and inductive reactance.
Resistance is determined by the length, cross-sectional area, and resistivity of the conductor, while the inductive reactance is affected by the inductance of the load and the frequency of the supply.
Resistance can also be affected by the 'skin effect' which causes the current to flow towards the surface of a conductor, reducing the effective cross-sectional area of the conductor. This is called 'a.c. resistance', and increases with frequency (at normal mains frequency, a.c. resistance is not markedly greater than d.c. resistance).

What is zero sequence impedance in transmission line?
In symmetrical components, there are three types of impedances - positive sequence (balanced), negative sequence (unbalanced), and zero sequence (ground). In a transformer, positive and negative are equal. Ground impedance is determined by the (same factors as the) positive sequence and is based on the flux paths available through the transformer core that can induce ground current.
How do you reduce dc voltage using zener diode?
To reduce DC voltage with a zener diode you place a resistor in series with the zener and setup for the reverse bias condition. You pick the resistor to bias the zener at the desired reverse current. You also have to consider the load across the resistor, across the zener, and across the target load. Often, this configuration is used to establish a reference voltage for something else, such as an op-amp controlled emitter-follower, but it is possible to use just the resistor and zener if you consider all the factors.
What four factors determine the amount of resistance in a circuit?
Material that makes up the wire, length of wire, diameter of wire, and temperature of wire
What does the 8 ohm speaker mean?
A speaker is a device that converts varying electrical signals into varying acoustic signals so that you can hear them as sounds.An 8 ohm speaker is a speaker that has a nominal impedance of 8 ohms. This means that is presents a load of 8 ohms to the amplifier over the range of frequencies that it is designed for. You should match the impedance of the speaker to the designed impedance of the amplifier. Failure to do so will result in inability to achieve rated power output, and it could lead to amplifier and/or speaker failure.There are other factors involved as well, such as power capacity, shape, resonant frequency, and expected enclosure design. Speaker designers spend a lot of time and money on selecting a particular speaker, and you should not arbitrarily substitute one for another without adequate justification.

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 are the factors that affect impedance?
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.
What is zero sequence impedance in transmission line?
In symmetrical components, there are three types of impedances - positive sequence (balanced), negative sequence (unbalanced), and zero sequence (ground). In a transformer, positive and negative are equal. Ground impedance is determined by the (same factors as the) positive sequence and is based on the flux paths available through the transformer core that can induce ground current.
What are the factors that can go into 147?
the factors are - 1,3, 7,21 ,49, and 147. this is how they connect - 1x147=147, 3x49=147, 7x21=147.
What two things is the value of inductance affected by?
There are four basic factors of inductor construction determining the amount of inductance created. These factors all dictate inductance by affecting how much magnetic field flux will develop for a given amount of magnetic field force (current through the inductor's wire coil): 1. Number of turns in the coil (N) 2. Length of coil (l) 3. Cross sectional area of coil (A) 4. Material (nature, or permeability) of coil: u(Greek meu) Inductance, L=(N^2 . u.A)/l

How do you connect a sub pump discharge line into your home drain?
This is a job for a qualified plumber, as there are various factors that have to be taken into account which cannot be made.
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 prompted Jefferson to sponsor the Lewis and Clark expedition?
he wanted to connect Mississippi to the pacific ocean.
When I try to connect to a server on Call of Duty World at War it takes more then 5 minutes sometimes to connect why does it do this?
It could be due to a slow internet connection; or if your NAT type is not on open it might take awhile. It also could just be a few different factors blocking your signal.
