Download Solution PDFIf two ammeters A and B require 20 mA and 30 mA current, respectively, to give a full - scale - deflection, then:
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
For meters, the sensitivity
Ifsd is the full-scale deflection in amps
It is expressed in ohm/volt
Calculation:
For Meter A
Ifsd = 20 mA
For Meter B
Ifsd = 30 mA
Hence, Meter A is more sensitive, which implies B is less sensitive than W1.
