Solved: The gap in the circuit seen in Fig. P7.86 will arc over whenever the voltage
Chapter 7, Problem 7.86(choose chapter or problem)
The gap in the circuit seen in Fig. P7.86 will arc over whenever the voltage across the gap reaches 30 kV. The initial current in the inductor is zero. The value of \(\beta\) is adjusted so the Thévenin resistance with respect to the terminals of the inductor is \(-4 \ \mathrm{k} \Omega\).
a) What is the value of \(\beta\)?
b) How many microseconds after the switch has been closed will the gap arc over?
