tan dx v Cx X tan d Or C tan dx 174 PRACTICAL ELECTRICITY. Prob. 66 : A tangent galvanometer is deflected 17° when inserted inseries with a solenoid and a Daniell cell. When a Grenet ced issubstituted the deflection is 31°. What is the relative strength ofcurrent through the solenoid when the… … Prob. 67 : If one ampere deflects the needle of a tangent galvanom-eter 5° how many amperes will deflect it 50° ? v T7 i /C^ n Cxtandx lxl.1918 10 a From Formula (ol) Cl=—r-—g—1 = —^ = 13.6 amperes. 0= 1 ampere, d = 5°, tan d = .0875, dx = 50°, tan dx = 1.1918.If a tangent galvanometer is…
