1.	When `2` amperes current is passed through a tangent galvanometer, it gives a deflection of `30^(@)`. For `60^(@)` deflection, the current must beA. `1 amp`B. `2sqrt(3) amp`C. `4 amp`D. `6 amp`
Answer» Correct Answer - D `i prop tan varphiimplies i_(1)/i_(2)=(tan varphi_(1))/(tan varphi_(2))` `implies 2/i_(2)=(tan 30)/(tan 60) implies i_(2)=6 amp`
