Why are measured values of resistors different from the stated values?

1: Resistors are manufactured with different tolerances, ie they're allowed to be both a bit above as well as below the target value. 2: If you're using a simple multimeter there's no telling how close the measured value is to the real value anyhow, once that you get down to the decimal places.

Why might there be discrepancies between the measured values of different blocks?
the blocks might not be the same size.
Did the the total voltage across the resistors does not depend on the resistor value?
It depends on where and how the resistor is placed in a circuit. A string of series resistors will split the voltage across all them depending on their values. All of the resistors in parallel will have the same voltage across all of them no matter what their resistance is.
What is the frequency of RC phase shift oscillator?
Without the simplification of all the resistors and capacitors having the same values, the calculations become more complex: Oscillation criterion:
Three 8.0-W resistors are connected in series What is their equivalent resistance?
Three 8.0-W resistors are connected in parallel. What is their equivalent resistance?
Give plausible reasons for any discrepancies between measured values and accepted values of wavelengths in an atomic spectra experiment?
Accepted values are often the average of many readings from many different experimental setups. Effects such as temperature or differences in the environment can have measureable effects, and your setup can be slightly different in subtle ways that affect your measurements. Electrical charges, pervasive magnetic fields, and other physical forces can change the actual effect or the accuracy of your instrumentation.

How will amps and current differ in a series if you get resistors with different resistance?
-- "Amps" and "current" are the same thing. Electric current is measured in units of Amperes. -- The current is always the same at every point in a series circuit, no matter how many resistors of the same or different values are in the circuit.
Why are the measured values of resistors different from the nominal values?
All electronic components have a tolerance value in their specification. For resistors, it is specified as a plus or minus tolerance. Typical ranges are 5%, 10%, and 20%, though you can get 1% and 0.1% (matched set) resistors if you want to pay the price. In addition, each measurement has systematic and random error associated with it. All of this must be considered when measuring the impedance of a resistor.
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
Does the current remains the same in a series circuit despite the different values if the resistors in the circuit?
current in series depends on values of resistors. more resistance less current will flow through and viceversa
Why was your measured pH level of the buffer solutions different from the calculated values?
A
What is your observation of resistors in series?
I observe that the total effective resistance of several resistors in series is the sum of the individual resistance values of the individual resistors.
How do you find the resistance of a series circuit with n identical resistors?
The total resistance of resistors in series is simply the sum of the resistance values of those resistors. If the resistors are identical, then you can multiply the resistance of one of them by the number of resistors in the circuit.
Carbon resistors are not available in market of each number of resistance why?
carbon resistors of standard values are manufactured because other values can be obtained by series and parallel combination of standard values. Moreover even standard values do not offer exact Resistance's will have tolerance
How do you find height?
Depends on what... it can be measured in different values such as inches, meters, yards etc.
How do you measure baby cereal?
Baby cereal must be measured according to instructions given on the package, because different brands have different nutritional values and different cooking instructions.
What is precision resistor?
A precision resistor is a resistor that has an actual value that is very close (or precise) to its nominal (or stated value). Therefore, precision resistors have a very degree of accuracy of being very close to their nominal values.
