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.
how to get theoretical voltage from given resistors and given experimental voltages
current is measured with the meter in series and voltage is measured with the meter in parallel of the load
...what readings? current? voltage? power? lux?
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).
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.
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.
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.
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.

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.
Experimental research involves manipulating variables to determine cause-and-effect relationships, while correlational research examines the relationship between two or more variables without manipulation. Experimental research allows for greater control over variables and enables researchers to draw stronger causal inferences compared to correlational research.

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.
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.
If you are referring to the voltage after the rectifiers in a powersupply, it is due to the voltage drop across the rectifiers.
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
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.
