Why is the theoretical value differ from the experimental value that you obtained from the voltage?
Your question is lacking in enough detail to give you a precise answer. However, it is not unusual in any experiment to get different experimental values depending on the controls you place on the experiment. For example, using Ohm's Law the Voltage is Current x Resistance.
Say you have a simple DC circuit with a 100 ohm resistor across a 10 Volt supply. Theory tell us that the current is equal to one-tenth amp (.1A). However, when you measure the current with an ampmeter the value is .15 A. Among other things the following things could go wrong. (Sample errors chosen at random to illustrate the point)
1.) The voltage really isn't 10 volts, it is only 9.8 volts under load.
2.) Your ampmeter isn't calibrated correctly and reading is off.
3. ) You have an analog ampmeter and there is a paralax error in reading the meter which throws off your measurement.
4.) The tolerance of the resistor is 20% so you don't really have 100 ohms.
5.) Temperature could play a factor.
6.) There could be a loose connection.
7.) Your little brother dripped jelly on the resistor effectively changing the end to end resistance, and so forth.

What is the percentage voltage drop for feeders?
In the CEC (Canadian Electrical Code) voltage drop for feeders is stated in rule 8-102. Voltage drop in an installation shall not exceed 3% in a feeder or branch circuit. This percentage may differ in the NEC (National Electrical Code).
Main factor which differ De mosfet from an e only mosfet?
An e only(enhancement) ÊMOSFET is off at zero gate-source voltage. Meanwhile, a de (depletion enhancement)ÊMOSFET is on at zero gate-source voltage.
How do power cords differ?
Power cords have different voltage rate, example 7A/125V cord can hold much voltage than 3A/125V. The higher the current flow can melt the lower type of power cord that is dangerous and can cause fire. Base on my knowledge there are different types of power cords according to the ampere and voltage needed.
Why do the reading differ for increasing and decreasing values of the lamp voltages?
at the time of decreasing lamp voltage as the temperature is already high the gas in the lamp is already in ionized state leading to different resistance ,but when increasing voltage the gas is not in ionized state it ready to ionize ,so there is slightly variation in resistance . :)
Why is the theoretical value differ from the experimental value that you obtained from the current?
The theoretical value is based on calculations and predictions made prior to the experiment, taking into consideration ideal conditions, assumptions, and factors. The experimental value is obtained through actual measurements during the experiment, which can be influenced by various sources of error such as equipment limitations, environmental factors, human error, or unknown variables. Discrepancies between theoretical and experimental values are common and can provide valuable insights into the accuracy and limitations of the theoretical model.
What is experimental approach?
Theoretical Approach is looking at the data and determining an outcome. Experimental Approach is performing the procedure and recording the actual oucome, which can differ from the theory or theoretical approach.
How does the experimental result differ from the theoretical in terms of accuracy?
Provided that the correct model is used, the theoretical probability is correct. The experimental probability tends towards the theoretical value as the number of trials increases.Provided that the correct model is used, the theoretical probability is correct.

Why theoretical and measured result differ?
Theoretical and measured results can differ due to various factors, including assumptions made in the theoretical model, simplifications that overlook real-world complexities, and experimental errors such as inaccuracies in measurement instruments or environmental influences. Additionally, variations in material properties and external conditions can lead to discrepancies. These differences highlight the need for continuous refinement of models and experimental techniques to improve alignment between theory and practice.
Why do theoretical values of equivalent resistance differ from experimental values?
Theoretical values of equivalent resistance can differ from experimental values due to several factors, including the tolerance and imperfections in the resistors used, variations in temperature affecting resistance, and the limitations of measurement techniques. Additionally, real circuits may have parasitic elements like capacitance and inductance that are not accounted for in theoretical calculations. These discrepancies highlight the importance of considering practical conditions when analyzing electrical circuits.
Why does the theoretical yield differ from the actual yield?
The theoretical yield is the amount of product that we predict will be obtained, calculated from the eqquation. The actual yield is the amount of product that is actually obtained at the end of the procedure.
Why is the experimental pH different than the theoretical value?
The experimental pH may differ from the theoretical value due to several factors, including measurement errors, impurities in the solution, or variations in temperature. Additionally, the presence of buffering agents or ionic strength can affect the dissociation of acids and bases, leading to discrepancies. Instrument calibration and the precision of pH meters can also contribute to inaccuracies in the experimental results.
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.
Why theoretical value of ethanol in distillation process is differ with experimental value?
While the distillation is going on ,at 94.6% ethanol-water mixture forms an azeotrope which hampers further distillation.So ethanol cannot be made 100% pure.But concentration of ethanol can be increased by breaking the azeotrope by addition of benzene in large amount.
Why does the experimental probability and theoretical probability differ?
The theoretical probability of event X is the proportion of event X out of N trials as N tends to infinity. Thus, if you flip a coin many times, you get closer and closer to 1/2 being H and 1/2 being T. This differs from experiment because all experiments take place with a finite number of trials.
Why is the peak voltage not exactly equal to the peak voltage of the alernating voltage and by how much it differ?
If you are referring to the voltage after the rectifiers in a powersupply, it is due to the voltage drop across the rectifiers.
How do a control sample and an experimental sample differ from each other?
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
