Question
a galvanometer has a resistance 60 ohm and is of 5mA full scale deflection.how would you modify it so as to get 0-10V voltmeter
Answers
at 10 V the current is 5 mA
so the total resistance is
... 10 / .005 = 2 kohm
so a (2000 - 60) ohm resistor is used in series
so the total resistance is
... 10 / .005 = 2 kohm
so a (2000 - 60) ohm resistor is used in series
