| A galvanometer has a 50 division scale. Battery has no internal resistance. It is found that there is deflection of 40 divisions when \[R=2400\,\,\Omega \].Deflection becomes 20 divisions when resistance taken form resistance box is\[4900\,\,\,\Omega \]. Then we can conclude: [JEE ONLINE 10-04-2016] |
