Time left 0:17:18 What is the self-induced EMF if the source current changes with time according to expression: I = a+bt, where a and b - constants? O a. EL = L * a, here L - inductance O b. EL = - L * b, here L - length O c. & = - L * b, here L - inductance O d. no correct answer O e. & = L * a, here L - length
