Q. Switch is open when transistor is in
Solution:
- With a zero signal applied to the Base of the transistor it turns ?OFF? acting like an open switch and zero collector current flows.
- With a positive signal applied to the Base of the transistor it turns ?ON? acting like a closed switch and maximum circuit current flows through the device.
- Therefore the correct option is A.
