Is utility voltage ie 110 VAC given as a RMS value or as a Peak value?
All AC voltages and currents are expressed as rms values, unless otherwise specified. So 120 V AC is an rms value.
The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
Why do the readings differ for increasing and decreasing values of the incandescent lamp voltages?
...what readings? current? voltage? power? lux?
When electricity travels long distances it is better to have it at higher voltages?
when transmission we usually use high voltages becoz at higher voltages current is less(p=vi,voltage is inversly proportional to current at constant power) so that we can minimize copper losses i2R losses.
Is AC voltage measured from Peak to Peak or from 0 to peak?
Both. When an AC voltage is measured and a number is reported, it is necessary to state that this number is rms value or peak value or peak to peak value.AnswerVoltages and currents are each normally expressed in root-mean-square (rms), unless otherwise stated. For example, when we talk about a '120-V service' or a '240-V service', we are expressing the voltages in rms values; it is unecessary to specify that these are rms values. For a sinusoidal waveform, Vrms = 0.707 Vpeak
What are the factors that affected the difference between theoretical and experimental values?
mostly, how good your theory is. Remember, experimental values are from reality.
Are the values of experimental and theoretical probability same?
Absolutely not. Experimental is practical and theoretically anything is possible.
How will you compare the theoretical value of G with the experimental values you obtained?
You'll find her G spot someday son
How do you compute a percent error?
% error = |experimental value - theoretical value|/theoretical value * 100% It is the absolute value of the differe nce betwee n the experime ntal a nd theoretical values divided by the theoretical value multiplied by 100%.
Was the Quantum Theory ever tested?
yes, it is the best tested theory there is. Theoretical and Experimental values agree to about 9 digits of accuracy.
What is the significance of negative values of voltages and currents?
Direction only. If you reverse the connections to your voltmeter or ammeter you get the same size readings but the directions are indicated to be the opposite way around, by reversal of sign.
Two ways that the theoretical yield differ from the actual yield?
A yield is received after a person does the experiment. Second, they can never be same values. We can only get close to theoretical yield but never attain similar values under normal experimental conditions.
Was quantum theory tested?
Quantum theory has been tested and theoretical and experimental values have been found to agree to more digits of precision than in any other theory tested against reality!
If The wall outlet has RMS value of 120VAC what is the peak value?
220 V is rms in europe if that is what you are getting at. Peak is at about 311 V.AnswerUnless otherwise stated, all a.c. voltages and currents are expressed in r.m.s. values.
What is the RMS volts formula for 3 phase system?
In three-phase systems, we always consider individualline or phase currents, or individual line or phase voltages. In other words, we treat currents and voltages no differently from single-phase currents or voltages (i.e. we don't 'combine' them because they are three-phase quantities). So these quantities are expressed in r.m.s. values.
How are chemical properties of matter characterized?
Correct characterization of matter chemical properties is possible by experimental studies; but theoretical methods exist for the approximate calculation the values for some chemical and physical properties.
What is numbers which are the results of an experiment?
These are the experimental values.
