In the network in the figure below find i090 ms using the di

In the network in the figure below, find i₀(90 ms) using the differential equation approach.

In the network in the figure below, find i_o(90 ms) using the differential equation approach. A the tolerance is +/-2%

When t= 90ms, inductor reaches its steady state and it acts as a short circuit,

Equivalent resistance of4K and12K resistor is 3Kohm

Now,current through 6Kohm resistor can be determined using current dividend rule as follows:

Io= (3K /(3K+6K) )*2 = 0.66 Amp
