Homework SourseObtain the induced emf Et due to the self inductance of a 25
Obtain the induced emf, E(t), due to the self inductance of a 2.56E-3 H inductor caused by the current i(t)=(4.67sin(240t))A flowing through the inductor. t is in seconds. Also indicate the maximum emf, Emax.
Obtain the induced emf, E(t), due to the self inductance of a 2.56E-3 H inductor caused by the current i(t)=(4.67sin(240t))A flowing through the inductor. t is in seconds. Also indicate the maximum emf, Emax.
Solution
induced emf = L*di/dt
= L*4.67*cos(240*t)*240
= 2.56*10^-3*4.67*240*cos(240*t)
= 2.87*cos(240*t) volts
maximum induced emf, Emf_max = 2.87 volts
