What the difference between power frequency inductance and high frequency inductance?
ShaunMarshgp7659
As the frequency becomes higher then its wavelength would decrease.
In case of mechanical waves such as sound waves higher frequency means higher the pitch. In Sanskrit it is known as 'shruthi'. Singers would sing at different shruthi.
In case of electromagnetic wave such as light, as frequency increases the colour changes. So highest frequency in the visible region will be the violet and the lowest is the red. Also the energy of the wave photon is given by the expression E = h nu, where nu is the frequency of the wave. So higher the frequency higher the content of energy in the photon compared to the lower frequency radiation.

∙ 8y agoAt high frequency less inductance is needed for an specific impedance and even the ferrromagnetic core could be eliminated BUT parasitic capacitance between turns becomes a problem as they adds susceptance with wrong sign so they are made of few turns threaded in a ferrite ring or an entangled coil to avoid long contact between loops (then stray capacitance). When a low frequency filter is needed they might be PI type with both types of inductors in serie and also different type of capacitors on parallel to ground as audio/power capacitors might have a parasitic inductance in series (coiled plates) that avoid RF to be eliminated.

∙ 14y agoHigh and low are comparatives.
Frequency is most often measured in hertz (cycles per second).
While 10,000 hertz is high compared to 5,000 hertz both are high compared to 100 hertz.

What is difference between resistance and reactance while both are measured in ohms?
Resistance is constant no matter the frequency applied. Reactance varies depending on the frequency of the power applied to it.
What happens to the current Amps flowing in a circuit when you raise or lower the frequency Hertz?
This question is not asking about household power circuits which typically have an almost constant frequency of 50 Hz or 60 Hz. If a circuit includes inductance and capacitance then the answer below, marked by *** is incorrect. That answer is correct for purely resistive loads only.An electric motor has inductance as well as resistance. The circuit inside a typical fluorescent light fixture contains a ballast - which has resistance and inductance - and a tube, which has capacitance, inductance and resistance. The currents flowing in the motor and the fluorescent light fixture would vary considerably if the frequency of the applied alternating voltage was allowed to alter.Two other common examples:i) a Hi-Fi or similar audio amplifier, driving a loudspeaker: the speaker has a coil in it which has inductance. The current (and hence the output power) of the speaker varies considerably with the audio frequency, typically between 20 Hz and 20,000 Hz (20 kiloHertz). For that reason different sized speakers - such as tweeters, mid-range, woofers and sub-woofers - each having different sizes of inductance and capacitance, are commonly used to produce the best "total overall sound output" from an amplifier.ii) a tuning circuit for a radio: this must use both an inductance coil and a tuning capacitor. The current flowing in those components varies enormously between "out-of-tune" and "in-tune" settings of the tuning capacitor which makes the circuit tune "in" and "out" of radio frequencies in a specific range which the tuning circuit was designed to handle. Radio frequencies range between 50 kiloHertz and hundreds of GigaHertz or more. Changing the power source from AC to DC may have an effect on the current drawn but is dependent on the nature of the load. Any device is designed for AC or DC operation but rarely both. *** Note: the following answer is incorrect except for purely resistive loads. ***The frequency of an AC voltage line has no effect on the current drawn for any given power. Voltage does have an effect on the current.
What does LT stand for in power transformer?
Transformer Inductance?
Why current lagging in the coil?
The coil consists of inductance. Due to inductance the current lags the voltage. So, the power factor is lagging.
In transformer if frequency are reduce then what happen?
t's basically a matter of the magnetizing inductive reactance which is inversely proportional to frequency. You want to keep the magnetizing current low to minimize power loss and avoid saturating the core. The higher the frequency, the lower the required inductance for a given inductive reactance and magnetizing current, thus the smaller the required core and/or number of turns on the windings.Magnetizing current is a normal parasitic byproduct of the transformer inductance and the applied voltage level and frequency. The amount of power that can be transferred through a transformer is usually limited by the transformer winding resistances and is unrelated to the magnetizing current. Thus core size goes up at higher power levels due to larger required wire size, not due to any core limitations.
What difference between RF power output watt and electrical power output watt?
The difference is in the output frequency.
Power factor is least in capacitance or resistance or inductance?
inductance
What are the 3 quantities of electricity?
Quantities or measurements related to electricity include:* Voltage * Current * Power * Energy * Capacitance * Inductance * Frequency
What is the difference between current (DC) and alternating current (AC)?
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
What is the difference between high frequency signals and low frequency signals in terms of 1 distance that can be traveled 2 transmit power required and 3 susceptability to EMI?

What will b the power factor of a series circut when r is made zero?
The power factor never depends on the resistance of a circuit. It depends on the equivalent inductance and capacitance in the circuit, and on the frequency of the power supply, even if the resistance is zero.
What are Examples of scalar?
Cost Temperature Speed Frequency Wavelength Electrostatic potential Electric charge Length Mass Volume Capacitance Inductance Resistance Energy Power
Why must the oncoming generator on a power system be parralleled at a higher frequency than that of the running system?
If the frequency of the oncoming generator is slightly higher than the system frequency, the phase angle between the system and generator voltages will slowly change at a frequency equal to the difference between system and generator frequencies.
How does reactive power change the Power Factor?
Power Factor is the relationship between the phase of the current and voltage which are each sine waves. When there is an inductance in a circuit the AC current waveform tends to lag the voltage. This causes a phase difference which reduces the Power Factor from a maximum of one to something less.
What is the relationship between inductance and power factor in an ac circuit?
for the purely inductance power,the power factor is zero because true power equals zero.here the power triangle would look like a vertical,because the adjacent (true power) side would have zero length....Engr. olunloyo university of lagos ,Nigeria
What is difference between SMPS And UPS?
The Main difference between a Switched Mode Power Supply and an Uninteruptable Power Supply is the function. SMPS are like a conditioner of electricity supply for a building, house, etc. UPS are the emergency backup power supply for vital computer based systems
What is difference between resistance and reactance while both are measured in ohms?
Resistance is constant no matter the frequency applied. Reactance varies depending on the frequency of the power applied to it.
