The rate of rise of current a thyristor can withstand is limited because
Answer: D
Correct answer: conduction spreads across the junction only gradually
Turn-on begins in a small area near the gate and the conducting region spreads outward at a finite velocity. If the current rises faster than the area grows, the whole current is carried by a small part of the junction, the local power density becomes enormous and the device fails. A series inductor limits the rate of rise to what the device can accept.
