SSC JE Electrical 2019 with solution SET-2 Observe the given figure. Find Thevenin’s resistance as seen from open-circuited terminals? 16 Ω 8 Ω 32 Ω 4 Ω 16 Ω 8 Ω 32 Ω 4 Ω ANSWER EXPLANATION DOWNLOAD EXAMIANS APP To find the Thevenin’s resistance the current source is open-circuited and the voltage source is short-circuited.
SSC JE Electrical 2019 with solution SET-2 In an alternator, if α = 60°, then find the pitch factor? √3/2 1 0 1/2 √3/2 1 0 1/2 ANSWER EXPLANATION DOWNLOAD EXAMIANS APP The factor by which, the induced E.M.F gets reduced due to short pitching is called pitch factor or coil span factor denoted by Kc. It is given asKc = cosα/2givenα = 60°Kc = cos60/2Kc = cos30°Kc = √3/2
