What if actual value - measured value is negative?
Then the measured value is larger than the actual value.
What is percentage error?
Given a true value and the measured value,the error is measured value - true value;the relative error is (measured value - true value)/true value, andthe percentage error is 100*relative error.
What is the value of an angle?
Angles are usually measured in degrees. They can also be measured in radians.
What is the equation for accuracy?
%error = (Actual value- Measured value) / actual value *100
Refers to How closley a measured value agrees with the correct value?
Accuracy.
What is resistence tolerence?
The typical spread (deviation) from the nominal value of the resistance of several resistors.
What is precision resistor?
A precision resistor is a resistor that has an actual value that is very close (or precise) to its nominal (or stated value). Therefore, precision resistors have a very degree of accuracy of being very close to their nominal values.
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.
What does Uo stand for?
U0 stands for the nominal rms-value of the line potential measured with respect to earth.
Difference between nominal and real variable?
A nominal variable is a variable measured in current dollars (the value of the dollar for the specific period discussed), and a real variable is a variable measured in constant dollars (the value of the dollar for the base period). That is, a real variable adjusts for the effects of inflation.
Why are measured values of resistors different from the stated values?
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.
Why does resistance value measured using multimeter differ from one decoded using colour band?
Resistors have tolerance. So does the multimeter. Standard resistors range from 20% (no fourth band), to 10% (fourth band silver), to 5% (fourth band gold). Resistors will not normally measure exactly what you expect, and proper circuit design must take this into account.The multimeter may not be calibrated correctly.
How do manufacturers of resistors indicate the value of the resistance?
They use a color code. Colored bands on the resistor that tell the value. Some precision resistors have their value written on them.
What are nominal values?
Nominal values are the values that a component is specified to be. For example, the nominal value of a 10K resistor is 10K. Its actual value may vary, though, based on its tolerance.
How does the experimental value compare to the real value for your resistors?
EXACTLY
What is the meaning of Nominal value of shares?
Nominal Value, Face Value or Par Value of Shares- Value of the Share as indicated on the Share Certificate. This is different from the Market Value of the Sare, which is the actual value of the share and the amount for which it can be bought or sold. The Market Value can be either higher or lower than the Nominal Value, depending on the performance of the company or the economic circumstances of the day. In essence, the Nominal Value of a Share is of little importance and most investors are concerned primarily, if not solely, with the Market Value of the Shares.
Will the resistors ohmic value increase if you increase the voltage?
No.
