what is the

1.range of the given ammeter a nd voltmeter???

2.least count of ammeter and voltmeter???

3.zero error in ammeter and voltmeter???

4.zero correction for ammeter and voltmeter???
plzz help me out experts i got to give my gernals wit these questins tmr......pls help me out smeone......

i) Range of the device is the limits of its value which it can measure. The range of a device is difference between its minimum marking of the scale to the maximum marking of the scale.

ii) Least count of a measuring instrument is the least value of physical quantity that can be measured accurately using the instrument.

It is represented as (total range of instrument / number of divisions on smallest scale)

For example the least count of a voltmeter is the minimum change that can be discerned.

iii) It is the incorrect reading that you have on your instrument when it is measuring something that you know should read zero.
For example, if you have an Amp Meter (to measure electrical current, you close the measuring contacts on a metal wire. There is no current flowing in the circuit. And yet your instrument reads a number different than zero. That number is your Zero Error.
iv) zero correction in measuring instruments mean calibrating them in such a way that the zero reading is is at a correct point in the graduations or lines.
You correct Zero Errors by pre-calibrating your instrument and adjusting all the readings of the future measurements that way.
