An inductor and a nonlinear resistor with resistance π = 500 + 250πΌ^2 Ξ© are connected in
series with a DC power source and a switch, The switch is initially
open and then is closed at time π‘ = 0. The current πΌ in the circuit for π‘ > 0 is determined from
the solution of the equation:
ππΌ/ππ‘ =πo/πΏ - (π /πΏ)*πΌ
For π0 = 500 π and πΏ = 15 Henries, using classical Runga Kutta method (fourth order R-K
method), determine the current as a function of time for 0 β€ π‘ β€ 0.1 π
