I do not understand what you mean by a 'bias circuit'. My circuit involves a 5V dc power supply. Then a LDR (or PHOTO RESISTOR) and variable resistor (10k, 100k, and 1M Ohms) connected to it. Two wire across the LDR are connected to a PC scope, and the PC scope connected to a computer (which...
Hello berkeman
First of all thanks for ur help!
My coursework involves using a stroboscope to flash light at different frequencies (5 times a second, 10 times a second... etc) on the LDR. This LDR is then connected to the oscilloscope where I see how long the LDR takes to respond to the...
Hello everybody,
This is my first post and I need some help in my AS Advancing physics OCR coursework.
My coursework is about seeing how well an LDR responds to various frequencies of light (eg 5Hz, 10Hz...). I am looking at responding times. I have got data about extra time taken to respond...
