Question

The expected value of the voltage across a resistor is '230' V. However, measurement yields a value of '303' V. Calculate:

a) Absolute error
b) Percentage error
c) Ab.

Answer 1

The absolute error in voltage measurement is 73 V, and the percentage error is approximately 31.74%. The note in part (c) appears out of context and cannot be calculated without further information.

Step-by-step explanation:

The calculation of absolute error and percentage error is essential in determining the accuracy and precision of measurements in the context of an electrical circuit. When a resistor has an expected voltage of 230 V, and a measured value turn out to be 303 V, one can ascertain these errors using the following formulas:

• Absolute error: The difference between the measured value and the expected value. In this case, absolute error = |Measured Value - Expected Value| = |303 V - 230 V| = 73 V.
• Percentage error: This represents how large the absolute error is in comparison to the accepted value. Percentage error = (Absolute Error / Expected Value) × 100%. Consequently, percentage error = (73 V / 230 V) × 100% ≈ 31.74%.

Part (c) of the question seems to be truncated or incomplete as “Ab” is not clear within the context provided. Additional information would be required to accurately respond to part (c).
