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.

DevinMeasured 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.
