darlington emitter design
I have a bridge circuit and it has 4 legs having a darlington (MJ10016) transistor connected with a 2N6079 and MJE210 in each leg. There is also one 0.05 ohm resistor connected to the emitter of each darlington transistors. My questions are:
1. What is the purpose of such a low ohm resistor in the darlington emitter?
2. If the darlington and the other two transistors in the leg burn due to overload (for example darlington explodes and a hole opens on the darlington's colector), what will happen to this 0.05 ohm resistor? Will it be shorted (zero resistance) or disconnected (infinite resistance) or it may not damage at all?
Regards
