I have a problem related with a transistor circuit. Please tell me whether my approach is correct or not.
I need to find the current through the 94.6ohms transistor.
My approach (Assuming PN voltage is 0.6V)
- Since the NPN transitor has 5.6V between the base and emitter, it will be biased. So, the voltage at the base of NPN will be 0.6V with respect to ground.
- So, current through 1K resistors will be (15V-0.2V)/2kohms = 7.4mA. (Vce = 0.2V)
Since the voltage at the top of 1k emitter resistor is at 0.6V, , the PNP transistor now, will turn as, the voltage between the base and the emitter is greater than 0.6V (As 15V-0.6V > 0.6V)
So,Current through the 94.6ohms is (15V-0.2V)/94.6Ohms = 156mA.
Is my calculation right?
