What part of the ohms scale of a meter are the most accurate resistance measurements made?
It really depends on what you are trying to get the resistance of. A piece of copper wire 30 feet long will only have a resistance of few ohms. A person can have a resistance of several million ohms. Making sure that your meter's leads are in good contact with whatever you are measuring is the best way to get an accurate reading.

What does OL indicate in a digital multimeter?
It usually stands for open loop, another way of saying there isn't continuity. Original answer: it means OVER-LIMIT beyond the limits of the meter to register, such as "infinity" on a resistance scale
When you read measurements on an analog multimeter you must look straight at the meter scales in order to prevent what?
Parallax error. Because there is a gap between the needle and scale, looking from either one side or the other of needle will make a difference in the observed reading. In high-end meters there was a general practice of putting a mirror behind a slot in the meter face. If the observer could not see the reflection of the needle in the mirror then the reflection was being obscured by the needle and the observer was perpendicular to, and therefore looking directly at, the scale.
How is The range of an voltmeter is increased?
The easiest way is to put a high resistance in series with the meter.You must know the input resistance of the meter. This is specified in the owner manual.Some meters are specified as having a certain input resistance.If a meter has a 1 Megohm input resistance, you can scale it up by a factor of ten by putting a 9 Megohm resistor in series with one of the probes.Some meters are specified in "ohms per volt".The Ohms/V rating can be different on different scales. If a meter is specified on the 600 volt scale as having "20,000 Ohms per Volt", then this means that the meter's resistance is 20,000 * 600, = 12,000,000 Ohms. 12 Megohms.To expand the meter's 600V scale to 10X the rating (6,000 volts), you would put a 108 megohm resistance in series with the probe. This resistance could be made up of ten 10 Megohm resistors, a 7.5 megohm resistor, and a 470 Ohm resistor. Even though that is only 107.97 megohms, the error is less than 1%.To expand the scale to 2X (1,200V) you would put a 12 megohm resistance in series with the probe.High voltage low power resistor strings can be put inside plastic, glass, or ceramic pipes. Consult the appropriate industry publications for recommendations.warning:Be careful when measuring high voltages. Never work alone.Most simple resistors are not rated for high voltage over 200-500 volts per each resistor and will arc or burn. Injury or death may result.I prefer to hook the "hot" end of the probe to the high voltage test point and let it hang there, and not to hold it by hand. Then I energize the equipment and take the readings. After I am done, I discharge the high voltage and safely remove the probe from the equipment.Poorly made or defective probes have killed people.
How can the scale balance weight be adjusted to ensure accurate measurements?
To adjust the scale balance weight for accurate measurements, you can add or remove weights on either side of the scale until it is balanced. This will ensure that the scale is properly calibrated and provides precise measurements.
At which end of the ohms scale are resistance measurement more reliable the zero end or the infinity end?
On an analog ohmmeter, measurements are more precise and more accurate at the zero end of the scale.
How accurate in a balance scale?
A balance scale is accurate to the precision of its measurements, which can vary depending on the scale's design and calibration. Most common balance scales have a precision of +/- 0.1 grams or better. Regular maintenance and calibration are key to ensuring accurate measurements.
How can I determine if a scale is accurate?
To determine if a scale is accurate, you can calibrate it using known weights and check if it displays the correct measurements.
Why the zero of the ohmmeter scale is usually at the right end of the scale and reading increase towards the left?
Because the meter is actually measuring the current through the resistor, and the two quantities ... current and resistance ... are inversely proportional. So when the meter measures more current, it has to read less resistance, whereas higher resistance will result in less current. So the numbers for resistance have to be printed "backwards" on the meter scale.
How to measure mass in physics and what are the methods used for accurate measurements?
In physics, mass is measured using a balance or a scale. The most common methods for accurate measurements include using a triple beam balance, a digital scale, or a spring scale. These tools provide precise measurements by comparing the mass of an object to a known standard.

What is the level of uncertainty associated with measurements taken using a digital scale?
The level of uncertainty associated with measurements taken using a digital scale is generally low, as digital scales provide precise and accurate measurements.
What scale of resistance does a megohm meter measure?
Mega = million Megaohm = 1000000 Ohms
How can I ensure accurate measurements using a balance weight scale?
To ensure accurate measurements using a balance weight scale, make sure the scale is calibrated properly before use. Place the object to be weighed in the center of the scale pan and wait for the balance to stabilize. Avoid touching the scale or the object while weighing. Read the measurement at eye level for accuracy.
Why should the experimenter avoid using the end of a meter stick when making a measurement?
The end of a meter stick is less precise due to potential wear and tear, leading to inaccuracies in measurement. Using the end can also introduce parallax error when aligning with a measurement scale. It is advisable to use the edge or the start of the scale for more accurate and consistent measurements.
How can I ensure accurate weight measurements while traveling with a portable bathroom scale?
To ensure accurate weight measurements while traveling with a portable bathroom scale, place the scale on a flat and stable surface, calibrate it before each use, and avoid moving or bumping the scale during measurement. Additionally, weigh yourself at the same time each day for consistency.
