What is the difference between a spectrum analyzer and a network analyzer?
spectrum analyser is single channel and cannot find ratio of phase and magnitude
What are the Causes of phase angle error and ratio error at Current Transformers?
RATIO ERROR The secondary current is less than the expected value. The secondary is less in magnitude. This diffence is known as ratio error. PHASE ERROR The angle between the expected and actual secondary current is known as phase error.
Can quality be expressed as the ratio of the volume occupied by the vapor phase to the total volume?
Quality can not be expressed as the ratio of the volume occupied by the vapor phase to the total volume. The exact definition of quality is "In manufacturing, a measure of excellence or a state of being free from defects, deficiencies and significant variations.
Which relationship is true of power factor?
Power factor is:the ratio of true power to apparent powerthe ratio of resistance to impedancethe ratio of the voltage across a circuit's resistive component to the supply voltagethe cosine of the phase angleetc.
Is your house 120 or 240?
It is usually 240. Two lines enter your house, carrying 120 volts each, but they are out of phase by 180 degrees, so the two combined entering your house provide 240 volts, which is necessary for powering central air conditioning systems. You also have the option of powering everything else in your house with 120 volts because of the phase difference of 180 degrees without the need of a 2:1 turns ratio transformer in your house. You breaker box in you basement is wired to take advantage of this phase difference, supplying the 240 and 120 volt sources to the places that they are needed. This is a huge advantage of AC power.
Difference between eutectic and pereutectic points?
> A eutectic transformation, in which a two component single phase liquid is cooled and transforms into two solid phases.> A peritectic transformation, in which a two component single phase solid is heated and transforms into a solid phase and a liquid phase.
What is the difference between a spectrum analyzer and a network analyzer?
spectrum analyser is single channel and cannot find ratio of phase and magnitude
What is voltage transformation ratio?
ratio of secondry voltage to primary voltage is called voltage transformation ratio
Does the formula used to calculate the turns ratio uses the phase voltages and phase current?
For a transformer, the turns ratio always applies between its primary and secondary windings. So the turns ratio for a three-phase transformer is the ratio of primary to secondary phase voltages, not between line voltages.
What is the difference between ratio estimation and regression estimation?
diferece between ratio and regression
What is the difference between a ratio and a proportion?
a ratio is a comparison between 2 things and a proportion is a ratio on each side of the = sign
Difference between adjusted and unadjusted odds ratio?
An odds ratio is the difference between the number of times that something happens and does not happen. An unadjusted odds ratio is a guess between what could or could not happen.
What is the difference between SINR and CINR?
SINR - Signal to Interference and Noise Ratio CINR - Carrier to Interference and Noise Ratio difference between those to is difference between carrier and signal carrier is signal who doesn't "carry" any information . it must be modulated( by phase,freq or amplitude) and those changes convey information. carrier is unmodulated signal signal is defined as useful signal which carries information SINR is power of signal to power of interfenence and noise ratio
What is the difference between a ratio and a prportion?
a ratio is a fraction of two numbers a proportion is = fractions
What is the difference between anabolic and androgenic steroids?
what are gonads what is the difference between androgen and estrogen?
What is a ratio that compares the difference between two output values to the difference between the corresponding input values?
something
What is the difference between odds ratio and Chi square?
none
