ASAP please CURRENT INCREASING FROM ZERO: Assume the switch is in position (b) for along time before it is switched to position (a) at t = 0. In position (a) Kirchoff'sloop rule results in a different differential equation for the current ¡(t).di(t)E-I(t)r-L = 0dtThe solution to this differential equation isI(t) = 1 (1-e-t/t),a. Determine the time constant of the circuit. Comment: theway to do this is to note that when t = ₂, the current is iI(1-e-¹) = 0.63 ....Where I.. = E/r is the current at t = ∞o and the time constant T₂ = L/r.4. The graph shows the current through the ideal inductor as a function of time after the switch is thrown to (a).b. The inductance is 1.2 H.

Assume positions are given in kilometers and that force is in newtons. Note: To make units easy, a newton times a meter is a joule. A newton times a kilometer is a kilojoule (kJ). But F returns newtons.
