Question
H.W.5: Determine i, i,, and v, for all t in the circuit shown in Fig.. Assume that the switch
was closed for a long time. It should be noted that opening a switch in series with an ideal
current source creates an infinite voltage at the current source terminals. Clearly this is
impossible. For the purposes of problem solving, we can place a shunt resistor in parallel
with the source (which now makes it a voltage source in series with a resistor). In more
practical circuits, devices that act like current sources are, for the most part, electronic
circuits. These circuits will allow the source to act like an ideal current source over its
operating range but voltage-limit it when the load resistor becomes too large (as in an open
circuit).
