JEE Main 2019 — Current Electricity Question with Solution
From: JEE Main 2019 (Online) 10th April Morning Slot
Question
A moving coil galvanometer allows a full scale
current of 10–4 A. A series resistance of 2 M
is required to convert the above galvanometer
into a voltmeter of range 0-5 V. Therefore the
value of shunt resistance required to convert the
above galvanometer into an ammeter of range
0.10 mA is :
