To reduce % error, you may-
1. Take an average over many observations.
2. Use the correct bridge for various measurements of resistance.(see variants of the wheatstone bridge)

When the resistor removed from a parallel connection of the circuit whether the resistance increase or decrease?
if we remove a resistor from the parallel connection the effective resistance value will be increased.
If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.
What cell that decreases in resistance with a decrease in illumination?
A photo resistor decreases in resistance as illumination increases. I don't believe there are any discrete components that accomplish what you are asking. You may need to use a photo resistor, combined with a transistor to invert this operation.
What is a resistor bank?
In simple way resistor bank contains number of resistors in series or parallel combination. They are connected in parallel to decrease the resistance and increase current rating and power dissipation.And they are connected in series to increase resistance and power dissipation.
Why doesn't current decrease in series resistance circuit though resistance opposes current?
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.

What will happen to the other resistor if the number of resistor decreases?
the voltage across that resistor will increase if it is in series with the other resistors. the current through that resistor will increase if it is in parallel with the other resistors.
What is resistor used for?
A Resistor Is Used To Limit The Current In A CircuitFurther AnswerA resistor is sometimes used to modify the natural resistance of a circuit -e.g. by adding a resistor in series, you can increase the natural resistance; by adding a resistor in parallel, you can decrease the natural resistance. Two or more resistors can be used to create a voltage divider -a method of obtaining a voltage lower than the supply voltage in a d.c. circuit.Use of resistor is to produce a particular amount of resistance to the flow of current

What is the purpose the light dependent resistor?
This is a Resistors,who's resistance decrease when light energy falls on its surface gradually.
If a carbon resistor increases in temperature its resistance will?
This depends on the type of conductor. If the conductor has a positive coefficient the resistance will increase. If the conductor has a negative temperature coefficient the resistance will decrease.

Is Watt Increase in series Connection Off Two Resistor?
No. The power (in watts) would decrease, due to the greater effective resistance.
What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
When the temperature increases thermistor resistance decreases?
Yes, that's correct. In a thermistor, which is a type of temperature-sensitive resistor, the resistance decreases as the temperature increases. This is because the conductivity of the thermistor material increases with temperature, causing the resistance to decrease.
