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.
Measured values of resistors can differ from stated values due to manufacturing tolerances, aging effects, temperature variations, or incorrect labeling. Different factors can contribute to these differences, resulting in slight variations in the measured resistance compared to the stated resistance marked on the resistor.

Why experimental calculations shoul use measured values of resistors rather than color coded values?
Experimental calculations should use measured values of resistors, because actual resistors can deviate slightly from their color-coded values due to manufacturing tolerances. Using measured values ensures more accurate results in experiments where resistor values play a critical role.
Why does resistance value measured using multimeter differ from one decoded using colour band?
The difference in resistance value measured using a multimeter and one decoded using color bands on a resistor could be due to imprecision in the resistor's color bands, aging of the resistor affecting its resistance value, or inaccuracies in the multimeter's measurement. It's essential to consider the possibility of tolerance levels in resistors, which can lead to variations in measured values.
Did the the total voltage across the resistors does not depend on the resistor value?
The total voltage across resistors in a series circuit is the sum of the individual voltages across each resistor. The resistor values do not affect the total voltage as long as they are connected in series.
How do you change frequency astable?
To change the frequency of an astable multivibrator circuit, you can adjust the values of the timing components - typically resistors and capacitors. Increasing the values will decrease the frequency, while decreasing the values will increase the frequency. Alternatively, you can also adjust the supply voltage or use a different type of oscillator circuit to achieve the desired frequency.
Why might there be discrepancies between the measured values of different blocks?
Discrepancies between measured values of different blocks could be due to factors such as variations in block composition, surface roughness, temperature, or the precision of measurement instruments. Additionally, human error during measurement or differences in measurement techniques could also contribute to discrepancies.

Do the resistors lie wwithin the tolerance limits?
To determine if the resistors lie within the tolerance limits, you need to compare the measured resistance values of the resistors with the specified range provided by the tolerance. If the measured resistance values fall within this specified range, then the resistors are within tolerance limits.
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
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.
Why was your measured pH level of the buffer solutions different from the calculated values?

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.
When Measured properties that have different values at different times are?
known as dynamic properties. These properties can change over time in response to various factors or conditions. Understanding the dynamics of these properties is important in fields such as physics, chemistry, and engineering.
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.
