    Engineering Electrical Circuity - Phototransistors

    If I were to swap the photo transistor for an LDR, could I then say that the current will increase as the light incident on the LDR increases in a series circuit?

    Could the same idea be applied if I were to swap the photo transistor for an LDR?

    Ah, but in this instance, for this experiment (bearing in my mind this is as secondary school standard), can it be used as a variable resister?

    So would the photo transistor act like a variable resistor in the following circuit: d

    Engineering Electrical Circuity - Phototransistors

    Thank you for your reply. I have just created the circuit and the current measured with the ammeter varied with the lux incident on the phototransistor. I would be very grateful if you could explain what's happening here and why the phototransistor does not act like a variable resistor. Many...

    Engineering Electrical Circuity - Phototransistors

    The following circuit was created. I would be very grateful if you could check that the what I have said about it is correct. "A phototransistor was connected in a series circuit as shown below. It is used like a resister in this case with a battery and multimeter measuring current. When the...
