    I got a question, at 2:56, the left side circuit the voltage Vce is right? Comparing with the right one, I think it would be Vcb.

      yeah, it's a typo.

    I have a question about the circuit diagram. The voltage source that connects the collector and base ( the lower right side voltage) is labeled Vce....I have never seen transistors before so I want to make sure if that is supposed to be Vce...I was thinking it would be Vcb or Vbc? I am not totally clear on what the labeling of the voltages signify. Thanks

    • @MichelvanBiezen
      @MichelvanBiezen  7 ปีที่แล้ว +1

      Vce is the voltage drop between the collector and the emitter.

  • @woodychelton5590
    @woodychelton5590 ปีที่แล้ว +1

    so Vce is the battery, but what is Vbe? I feel like in other examples I tend to see a resistor there instead. Is it's purpose to control the magnitude of the base current?

    • @MichelvanBiezen
      @MichelvanBiezen  ปีที่แล้ว +1

      Typically a resistor is placed on the circuit for the base current in order to limit the base current.

  • @dlrmfemilianolako8
    @dlrmfemilianolako8 2 ปีที่แล้ว +2

    Professor I have a question for that , is I emitter constant or not? Because if we have a small base current we will have large collect current ....

    Ohh there is a mnemonic for remembering the NPN transistor symbol that is NOT Pointing In ,which indicates the direction of the emitter.

    Thank you for great videos. I think, in the place of Vce in the video should be Vcb. Negativ terminal of Vce would connect to negativ side of Vbe (Emitter).

  • @fernandoluis53

    so if the current at the base is 0, will the current at emitter be equal to the current at the collector?

    • @fernandoluis53
      @fernandoluis53 8 ปีที่แล้ว

      +yashfernandojain I know you said that if u stop the base current, you will stop the current from collector to emitter? then how does this equation make sense -> Ie=Ib+Ic if Ib = 0 we get ====> Ie=0+Ic ====> therefore there is still current flowing at the emitter when base current is 0

    • @MichelvanBiezen
      @MichelvanBiezen  8 ปีที่แล้ว +2

      +yashfernandojain
      That equation is only valid if there is a base current. Transistors are made to allow a current to flow from the collector to the emitter if there is a base current.

    Ha ha-- this is a great explanation but I was constantly thrown off when he described the direction of current flow. I was always taught using electron flow. I know using hole flow is common, and it's the same analysis, I just mostly learned the opposite
