Please quickly i have 10 min answer please
A transistor is used as a switch. Assuming that the total power loss in the transistor (Collector and Base losses) is equal to 108.5 W. If the ambient temperature is 25°C, and the thermal resistors are given as: Ric = 0.4°C/W, Ros = 0.1°C/W, RSA = 0.5°C/W, then the junction temperature T, would be equal to: To T, W Ric TS Res OP RA ΤΑ Select one a 555 b. 1115 885 d235c
