Current Electricity question

2016 · 10 Apr · Shift 1 · Q62

JEE MainPhysicsCurrent ElectricityMCQ+4 / −1
A galvanometer has a 50 division scale. Battery has no internal resistance. It is found that there is deflection of 40 divisions when R = 2400 Ω\OmegaΩ. Deflection becomes 20 divisions when resistance taken from resistance box is 4900 Ω\OmegaΩ. Then we can conclude : JEE Main 2016 (Online) 10th April Morning Slot Physics - Current Electricity Question 284 English
