    How Does Inductor Behavior Affect Circuit Current at t = 0.224 s?

    I got one answ... I(0.224) = 1.2*(1 - e^-2) = 1.038 A :::: 5 + 5*10/(5 + 10) = 8.33 30/8.33 = 3.6 A 5*10/(5 + 10)=3.33 3.33*3.6 = 12 V 12/10 = 1.2 A so I have that now how would I find the current in the switch at that same time?

    How Does Inductor Behavior Affect Circuit Current at t = 0.224 s?

    i = V/R(1 - e^-t/L/R + V/5 = (30 - V)/5 i thought that was what i was doing

    Inductance and RL circuits help

    If the switch is closed at t = 0, find the current in the inductor at t = 0.224 s. Answer in units of A. & Find the current in the switch at that same time. I know that i must use i = V/R(1 - e^-t/L/R) but can't seem to get the right answer. Any help is appreciated...5 ohms...

    What is the Capacitance and Potential Difference of a Coaxial Cable?

    A 31 m length of coaxial cable has a solid cylindrical wire inner conductor with a di- ameter of 2.042 mm and carries a charge of 7.32 μC. The surrounding conductor is a cylindrical shell and has an inner diameter of 6.748 mm and a charge of −7.32 μC. Assume the region between the...
