    How does photocell output change with distance from infrared point source?

    Is a photoresistor the same as an LDR, and if so could I use just a normal LDR to detect infrared?

    How does photocell output change with distance from infrared point source?

    In my plan should I say that I was using a photocell, or would I have to be more clear and say that I will use a photoresistor.

    How does photocell output change with distance from infrared point source?

    Just out of interest do I need to include a graph of what i expect to see? Thanks Physicsameture you've been a great help

    How does photocell output change with distance from infrared point source?

    Just to clarify The photocell circuit does not require a battery as the photocell produces its own current, which I will measure using an ammeter. Im sure its been said before, but would somebody tell me if this is right? And I am probably being stupid but would the photocell circuit...

    How Does Distance Affect Photocell Output?

    Will you please help I am confused Ive been told by my physics tutor to connect the photocell to a battery, and take a reading of the current. Would this work? THANX
