Question

The current in and the voltage across a 10H inductor are known to be zero for t 스 0. Ihe voltage across the inductor is given by the graph in Fig. P6.9 for t 2 0.

6.9 The current in and the voltage across a 10H inductor
are known to be zero for t < 0. The voltage across the
inductor is given by the graph in Fig. P6.9 for t 0.
Transcribed Image Text:6.9 The current in and the voltage across a 10H inductor are known to be zero for t < 0. The voltage across the inductor is given by the graph in Fig. P6.9 for t 0.
a) Derive the expression for the current as a func-
tion of time in the intervals 0 <t s< 25 ms,
25 ms <ts 75 ms,
125 ms <t s< 150 ms, and 150 ms <t < ∞.
75 ms <t < 125 ms,
b) For t > 0, what is the current in the inductor
when the voltage is zero?
c) Sketch i versus t for 0 st< ∞.
