What is its area in square mils? 400000 square mils 4000 square mils 40000 square mils 400 square mils 400000 square mils 4000 square mils 40000 square mils 400 square mils ANSWER EXPLANATION DOWNLOAD EXAMIANS APP 1.6 inches = 1.6 inches x 1,000 mils per inch = 1,600 mils0.25 inch = 0.25 inch x 1,000 mils per inch = 250 milsArea = 1,600 x 250 = 400,000 square mils
MGVCL Exam Paper (30-07-2021 Shift 3) A conductor having surface density is embedded in a dielectric medium of permittivity. The electric field in the medium is E. If it is known that the pressure p on the conductor surface is equal to the electric energy density in the medium, then p (in SI unit)is given by σ²/(4π) σ/(4πε) σ²/(2ε) σ²/(2πε) σ²/(4π) σ/(4πε) σ²/(2ε) σ²/(2πε) ANSWER EXPLANATION DOWNLOAD EXAMIANS APP As the point is near to the conductor will act as infinite sheetElectric field (E) is given by:E = σ²/(2ϵ)
MGVCL Exam Paper (30-07-2021 Shift 3) A three phase four pole 50 Hz induction motor has a rotor resistance of 0.02 Ω/phase and stand-still reactance of 0.5 Ω/phase. Calculate the speed at which the maximum torque is developed. 1525 rpm 1440 rpm 1500 rpm 1475 rpm 1525 rpm 1440 rpm 1500 rpm 1475 rpm ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Condition for maximum torque,Sm = R2/X2= 0.04Ns = (120*f)/P= (120*50)/4= 1500 rpmS = (Ns - Nr)/NsNr = Ns(1 - Sm)= 1500*(1 - 0.04)= 1440 rpm
