yes , there is a difference because there is a tolerance
To calculate the percentage error in a measurement or calculation, you first find the difference between the measured or calculated value and the accepted or true value. Then, divide this difference by the accepted value and multiply by 100 to get the percentage error. The formula is: Percentage Error (Measured Value - Accepted Value / Accepted Value) x 100
No, resistors are measured in ohms, not amps. Ohms represent the resistance offered by the resistor to the flow of current, whereas amps (amperes) represent the measure of current flowing through a circuit.
A meter bridge is used to measure an unknown electrical resistance by comparing it with a known resistance. It works on the principle of Wheatstone bridge. By balancing the bridge circuit, the value of the unknown resistance can be calculated accurately.
Resistance is the property of a conductor, which determines the quantity of current that passes through it when a potential difference is applied across it. A resistor is a electrical componet with a predetermined electrical resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.. depending on how much current you want to pass through a circuit, you would design the circuit with the required resistors
Take the correct value, subtract the value you got, and then divide that figure by the correct value. Then take the absolute value of that and multiply by 100. For example, say I weighed something and got that it was 2.5 grams, but it really was 2.7 grams. 2.7-2.5=.2. .2/2.7=.074. .074*100=7.4. Thus, I had 7.4% error. Another example: 16-15=-1. -1/15=-.067. .067*100=6.7% error.
what is the diference betwean calculated and maesured value
A simple subtraction. Take the smaller from the larger
Tolerance indicates how much the measured value of a resistance is different from its theoretical value, and it is calculated using percentages.
To calculate the percentage error in a measurement or calculation, you first find the difference between the measured or calculated value and the accepted or true value. Then, divide this difference by the accepted value and multiply by 100 to get the percentage error. The formula is: Percentage Error (Measured Value - Accepted Value / Accepted Value) x 100
Accuracy = Measured or calculated value/True Value
The percent error is calculated by taking the absolute difference between the measured value and actual value, dividing it by the actual value, and then multiplying by 100. If the actual weight is not provided, the percent error cannot be calculated.
Percentage error in p is calculated by taking the absolute difference between the measured value and the true value, dividing by the true value, and then multiplying by 100 to get the percentage. The formula is |(measured value - true value) / true value| * 100.
No, resistors are measured in ohms, not amps. Ohms represent the resistance offered by the resistor to the flow of current, whereas amps (amperes) represent the measure of current flowing through a circuit.
No, the absolute error cannot be negative. Absolute error is defined as the absolute value of the difference between the measured value and the true value, which ensures that it is always non-negative. It is calculated as |measured value - true value|, and since absolute values are always positive or zero, the absolute error itself will also never be negative.

V = I*R, so take 100 volts and divide it by the value of the resistance to get the current. Current is measured in amperes.
