bipolar junction transistors
I need help with bipolar junction transistors?
1 – When a transistor circuit is checked out, a very low resistance reading should be obtained between C and E is a good transistor. True or False 2 – In a bipolar junction transistor, the collector current is controlled by a collector voltage BC base current-collector resistance or all of them? 3-VCE is approximately equal to that when a transistor switch is saturated? VB VC ab-cd = 0.2 V or 0.7 V 4 – When a transistor switch is on, the collector current is limited by the current base-b-collector resistance of the C-voltage d-base or base resistance?
1> False 2> The base current controls the collector current (BJT is why it is called a current control device) 3> 0.2 V (When the switch is in saturation, it is almost a short circuit) 4> The collector resistance determines the collector current when the transistor is on
