Why a strip of mirror is mounted under the needle and near the scale of a voltmeter How this may help to rreduce errors while taking a reading?
The strip of mirror is mounted to help eliminate parallax errors when reading the value on the scale of the voltmeter. By aligning the needle's reflection with its actual position on the scale in the mirror, the observer can avoid viewing the needle from an angle, which could result in an inaccurate reading due to parallax. This setup ensures a more precise and accurate reading of the voltmeter.

What causes an error in reading a voltmeter?
Errors in reading a voltmeter can be caused by factors such as poor connection of the voltmeter probes to the circuit, incorrect range selection on the voltmeter, and external electromagnetic interference affecting the measurement. Additionally, using a voltmeter with low battery or a faulty internal circuit can also lead to erroneous readings.
Why do you use a meter bridge for measurements rather than a voltmeter and ammeter?
A meter bridge is used in some cases for precise resistance measurements. It can be more accurate than using a voltmeter and ammeter because it eliminates errors from contact resistance and internal resistance of the instruments. This method allows for more accurate determination of resistance by comparing two resistance values directly.
Can a magnetic compass reading change?
Yes, a magnetic compass reading can change due to fluctuations in the Earth's magnetic field, interference from nearby magnetic objects, or errors in calibration. It is important to regularly check and correct the compass reading for accurate navigation.
Why do we consider lower meniscus in acid hematin while taking a reading?
We consider the lower meniscus when reading acid hematin because the meniscus is the curved surface of a liquid, and the lower meniscus represents the bottom of the liquid column. This ensures that the measurement is accurate and consistent, as reading at the same point each time minimizes errors in volume determination.
How to measure the electromotive force (EMF) of a cell accurately?
To measure the electromotive force (EMF) of a cell accurately, use a voltmeter with high precision and connect it to the terminals of the cell. Ensure the cell is not connected to any external circuit during the measurement to prevent errors. Take multiple readings and calculate the average to minimize inaccuracies.

What is the Disadvantage of using an ammeter and voltmeter to measure resistance?
There will be errors. The error comes from the measured resistance size of the decision.
