Measuring ohms, or resistance, is typically done with the circuit switched off to avoid damaging the multimeter and to ensure accurate readings. When the circuit is energized, the presence of voltage can affect the resistance measurement and may lead to incorrect values. Therefore, it's essential to turn off power before measuring resistance to get reliable results.
Any contamination can affect results.
Yes. Measuring resistance involves imposing a small current through a device and measuring the voltage drop. If there were any other source of voltage, the reading would be in error. You could also damage the ohmmeter if there were an external voltage source. You should also take the device out of circuit before measuring it, so as to not bias the results by the resistance of other devices in the circuit. It all depends on the situation, for which you are responsible for evaluating before you start.
so that you can compare the results with the real medicine.
You measure it indirectly using a known load resistance and measuring supplied current. Loading of the ammeter should be known as well, and the load resistance should be made relatively small to get accurate results.
Accurate measurements help allow for accurate results in cooking. A perfect example is in baking.
Yes, it is important to have accurate measurements in an experiment because they can directly impact the validity and reliability of the results. Inaccurate measurements can lead to flawed conclusions and unreliable data. Using precise measuring instruments and techniques helps ensure the quality of the experiment.
the results were inconsistent and inconclusive
Measuring things that you want to change is important because it allows you to track progress, identify areas for improvement, and make informed decisions based on data. By measuring, you can set goals, monitor outcomes, and adjust strategies to achieve desired results effectively.
It is so that the experiment is a fair test. In order to protect the integrity and / or accuracy of the experiment and its results, you have to be able to control all the variables so that you know exactly why something is happening. If you do not control the variables, then one of them could be the reason for the results, and you won't be sure why you got the results you did.

Accurate reporting of procedures and results is important to ensure the reliability and replicability of scientific findings. It allows other researchers to verify the results, build upon previous work, and identify potential errors or biases. Transparency in reporting also helps maintain the integrity of the scientific process and contributes to the advancement of knowledge in the field.
A procedure to detect defective filter cartridges is filter integrity testing. Based on the test results the quality and performance of the filter can be determined.
Analyzing results Measuring Gathering data
The most important part of laboratory equipment would be two things goggles and gloves. Goggles protect you from any splashes or chemical reactions. Gloves protect your hands just in case something spills.
Integrity means honesty and faithfulness. Integrity involves owning up to one's mistakes and taking responsibility for one's error. Some people try to blame others when the errors are themselves. Integrity and responsibility go hand and hand.
