EMI questions

  1) static & dynamic errors.list out types of errors in measurement.

2)(a)  what are required of shunt? how a basic ammeter converted to multi range ammeter?
    (b) a 10 ma d'arsonwal meter moment having an internal resistance of 100 ohms is used to converted into a                  multi range ammeter having range of 0-1A,0-5a & 0-20A. determine the value of shunt resistance required.

3) (a) how a PMMC can be used as a multi range voltmeter & a series type ohmmeter
