1.	In a tangent galvanometer a current of `0.1 A` produces a deflection of `30^(@)`. The current required to produce a deflection of `60^(@)` isA. `0.2A`B. `0.3A`C. `0.4A`D. `0.5A`
Answer» Correct Answer - B `i prop tan varphiimpliesi_(1)/i_(2)=(tan varphi_(1))/(tan varphi_(2))` `implies0.1/i_(2)=(tan 30^(@))/(tan 60^(@))=1/3impliesi_(2)=0.3A`
