What do we measure in the experiment of parallel resonance?

At resonance there will be a large circulating current between the inductor and the capacitor due to the energy of the oscillations, then parallel circuits produce current resonance. We can calculate the current in each branch and then add together or calculate the admittance of each branch to find the total current.

What is the condition for resonance in RLC series circuit?

Series Resonance The resonance of a series RLC circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase. The sharp minimum in impedance which occurs is useful in tuning applications.

What are the causes of errors in measurement?

An object’s volume changes due to fluctuations in temperature, which also leads to changes in the object’s length. This applies not only to the measurement target but also to the measuring instrument….(1) Errors caused by temperature.

How do you find the source of error in an experiment?

One method of measuring error is by calculating absolute error, which is also called absolute uncertainty. This measure of accuracy is reported using the units of measurement. Absolute error is simply the difference between the measured value and either the true value or the average value of the data.

What is the condition for resonance to occur?

The conditions to produce resonance in an object are: The object must have a minimum of one natural frequency of vibration. The object must be driven by an external force of vibration. The frequency of the external vibrating force must be similar to the object’s natural frequency of vibration.

What are common sources of error in physics laboratory experiments?

Common sources of error in physics laboratory experiments: Incomplete definition (may be systematic or random) — One reason that it is impossible to make exact measurements is that the measurement is not always clearly defined.

What is the difference between precision and measurement error?

Measurement error is the amount of inaccuracy. Precision is a measure of how well a result can be determined (without reference to a theoretical or true value). It is the degree of consistency and agreement among independent measurements of the same quantity; also the reliability or reproducibility of the result.

What are the sources of systematic error in measurement?

Some sources of systematic error are: Errors in the calibration of the measuring instruments. Incorrect measuring technique: For example, one might make an incorrect scale reading because of parallax error. Bias of the experimenter.

How do you correct systematic errors in voltages?

If a systematic error is discovered, a correction can be made to the data for this error. If you measure a voltage with a meter that later turns out to have a 0.2 V offset, you can correct the originally determined voltages by this amount and eliminate the error.
