Yes, there may be differences between measured and calculated values of resistance. Measured resistance is obtained through direct measurement using a multimeter or other relevant instruments, while calculated resistance is determined using Ohm's Law based on the circuit components. Factors such as temperature, component tolerances, and measurement errors can lead to discrepancies between the two values.
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
The error in a measurement is the difference between the measured value and the true value. It is calculated by subtracting the true value from the measured value. The percent error is then calculated by taking the absolute value of the error, dividing it by the true value, and multiplying by 100.
Resistance is the measure of opposition to electrical current flow in a material, measured in ohms. Resistivity, on the other hand, is an intrinsic property of a material that quantifies how strongly it resists the flow of electric current. It is specific to the material and is used to calculate the resistance of a given object based on its dimensions.
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.
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.
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.
error
Measured refers to data collected through observation or experimentation, while calculated involves using mathematical equations or models to derive values based on known parameters. Measured values are obtained directly from experiments, whereas calculated values are determined through mathematical manipulation.
