Question

Q4. In the meters shown below, if you have to choose them based on their abilities which is independent of time then analyze and justify your selection for each instrument. Discuss them in detail. Meter 1 Meter 2 Meter 3 MA ES 600 400 NERES 200 1000 AC 1200 AMPERES CHRIM Meter 4 Meter 5

plzz i want explain in detail ...!

Answer 1

4) a while we are going to measure time invariant quantity ime independent) ? that means DC quamelty, meter showed capable to mealne - average value. → Both pumc& MI instruments can measure average value. & so we can select the meters which is having linear con non-linear scale.

We know that always pmm meters are having a linear scale and these are calibrated for average value. pmme Td L BINA Td QI roxI Deflection is directly proportional to current Hence ff is having linear scale. - mi meters are having non-linear scale and ho are caliserated for ome values, But Qt can measuese average value algo, IL ONHO31 ya (Td xD2 Tox22] AS deflection is directly proportional to square of the current. Hence it is having nontori non-linear scale. - As melens 265 having innear Scall. Hence thenge are pmme type And which will give you the best result for meagument of quamolliee wobech are time independent - 2 best medens are But can measure 965. (you can select these mereras only with all these 5 medens.
