Please help me with this simple circuit, which is creating lots of confusion due to different results from theoretical calculation and SPICE simulation.
Ques: In this circuit switch is closed for time t = 1sec, and then switch is opened and we have to find current through iductor and diode after time t = 2sec when switch was opened.
I solved it using V=L*(ΔI/Δt), and when simulated the circuit in LTSPICE the results were completely different. my calculation gave value of current after time t=2sec from opening the switch as I=7A through inductor whereas in LTSPICE simulation value came out aound 4A.
it's L=1 Henry only, sorry it was typo before
Circuit description: Ideal inductance (L=1 Henry), ideal diode and resistance of R=1ohm.
