    How Can You Analyze LDR Response to Light Frequencies in AS Physics Coursework?

    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...

    How Can You Analyze LDR Response to Light Frequencies in AS Physics Coursework?

    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...

    How Can You Analyze LDR Response to Light Frequencies in AS Physics Coursework?

    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...
