Question

A galvanometer has a resistance of `15.0Omega` and the meter shows full scale deflection for a current of 2.0 mA. How will you convert this meter into (i) an ammeter of range 0-5.0A and (ii) a voltmeter of range 0 to 15.0V? Also determine the resistance of the meter in each case.

Answer 1

Correct Answer - (i). 0.006 `Omega` in parallel, `R_(A)=0.006Omega`
(ii). `7485Omega` in series, `R_(V)=7500Omega`
