What is the power factor of a coil?
Power factor is the cosine of the phase angle between voltage and current. In a purely resistive load, like a toaster, since the phase angle is zero, the power factor is 1. In a theoretically purely inductive or capacitive load, with the phase angle at 90 degrees, the power factor is 0. Power factor is also the ratio of apparent power versus true power, or watts versus volt-amperes.
What is quality factor for choke coil?
the quality factor for choke coil is impedence divided by resistance in a given circuit
Why channel spacing is 200khz in gsm?
Simply because of the band-width required to transmit and receive calls. If the channel spacing was narrower - they'd need to reduce the band-width - which would reduce the amount of data they could transmit.
What is the use of finding the bandwidth of an amplifier?
A: Any amplifier will have greater band with if operated open loop. It will also be very unstable so negative feedback is implemented for that reason. There is some drawback when feedback the band width of the amplifier decreases, So is important to find out if the amplifier when stable will it have the band width required
What is voltmeter with a broad band width has noise and sensitivity?
high noise level and low sensitivity

What is the band width of ask?
ask band width
Non-ideal properties for op-amp.?
limited band width and very low amplification factor, to begin with hi voltage and current offset
What does 14mm mean for a watch band?
MM is millimeter. Determines the width of the piece. The watch band is 14mm in width.
Relation between cutoff frequency and bandwidth?
The relation between cut off frequency (fc) and band width is as follows: fc=Q*B.W where Q=(fL*fH)^1/2/(fH-fL) Q is quality factor. fL is low frequency. fH is high frequency.
When was Never Mind the Quality Feel the Width - film - created?
Never Mind the Quality Feel the Width - film - was created in 1973.
How do you get rectangles from a list of factor pairs?
The factor pairs are the length and width of the rectangles.
What is Q factor?
In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how under-damped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its center frequency.Q factor, a measurement of a resonant system's relative bandwidthQ factor (bicycles), the width between where a bicycle's pedals attach to the cranksQ factor (digital communications), a way of representing bit error rates in dB
What is the importance of the quality factor Q of a tuned amplifier?
If quality factor is greater then bandwidth will also greater
If the length and width of a field are scaled by a factor of 1.5 what factor will the area of the field increase?
2.25
