i cant understand upon what bais they made such a transition
What is that thing? A 12uV voltage source backwards? Or is it supposed to represent the final current through the inductor?
its some step function
which represents a voltage sorse
-t says its zero from t>0 and forward
Oh, so it's meant to replace the switch with a step function. Okay.
its acts like a switch
its a step function of -t
from t>0 and forward it goes to zero like a switch
but how they got its coefficient of the step function?
i cant see how its the same as the original circuit
It looks to me like it generates a 12V that is opposing the other 12V supply, up until t=0 when it goes off and lets the other 12V supply be the only supply in the circuit. for t<0 when the two 12V supplies oppose each other, there is no net voltage to drive a current around the circuit.
can you describe how its like the original circuit?
how its opposing ??
its plus 12
not minus 12
ahh thanks :)
