First off, do photodiodes and phototransistors do exactly what they say on the tin? Will they allow current to flow when they detect light?
Second, is the ambient light in a room with the lights on (for arguements sake, one 60W bulb, 10 feet away in an enclosed room) enough to allow current to flow? And lastly, how quick would they respond to the light coming on or off? For example, if I flicked the light switch off and then on again as fast as I could, would that mean that the diode would stop current flowing for a while?
Thanks all.
