What are the possible errors in potentiometer experiment?
The length measurement may have error if the potentiometer wire is not taut and along the scale on the board. 4. Multiple key jockey may not have correct alignment with the scale.
What errors can occur in a circuit experiment?
Common sources of error include instrumental, environmental, procedural, and human. All of these errors can be either random or systematic depending on how they affect the results. Instrumental error happens when the instruments being used are inaccurate, such as a balance that does not work (SF Fig.
What are sources of error in resistivity experiment?
This paper discusses a number of sources of systematic errors including: Errors in the system gains or calibration of voltage and current monitors, Leakage and coupling in multiplexers, cables and wires, and Electrode aging and impedance effects.
What are the sources of errors and precautions of a current voltage experiment?
The following errors may result: Area of cross section may not be uniform along the wire length. Unavailability of thick connecting wires at the time of the experiment. Reading error may arise while reading the pointers of ammeter and voltmeter.
What are the two faults in potentiometer?
The potentiometer will not show the balanced point if the emf of the battery that has to be tested is greater than the standard cell. The common point at the potentiometer wire and the source to be compared must be at the same polarity in order to get the balance point.
What are the possible causes for one sided deflection in potentiometer?
Expert Answer:
- The possible causes for the one sided deflection in the galvanometer during potentiometer experiment can be:
- The potential difference between the ends of the potentiometer wire or the emf of the cell connected in the main circuit may not be greater than the emf of the cells whose emf are to be compared .
What are the possible sources of error in the experiment on series RLC circuit?
Possible sources of error in this lab include random intrinsic error in the oscilloscope, resistor, inductor and capacitor, and also in measurements.
What are the two possible faults you would look for in a potentiometer circuit for measuring emf?
(i) The emf of the cell connected in main circuit may not be more than the emf of the primary cells whose emfs are to be compared. (ii) The positive ends of all cells are not connected to the same end of the wire.
