Find i(t) on Inductor

at t=0 10 Q 10 A 20 Q 2 H
Transcribed Image Text:at t=0 10 Q 10 A 20 Q 2 H
Expert Solution
Step 1

Given circuit:

Electrical Engineering homework question answer, step 1, image 1

The switch has been closed for a long time and is opened at t=0.

So, the given circuit at t<0 is shown in the figure below:

At t=0-, the inductor behaves as a short circuit.

Electrical Engineering homework question answer, step 1, image 2

Assuming a node voltage V as shown in the figure above such that,

i0-=VR

where

R=5∥10=3.33 Ω

Applying nodal analysis at node V,

V20+V5+V10=10V120+15+110=10V0.35=10V=100.35=28.57 V

So, inductor current at t=0- is:

i0-=28.573.33=8.58 A

As the inductor current doesn't change instantaneously, so

i0-=i0+=i0=8.58 A
