This transistor switching circuit uses a mosfet transistor, a voltage divider (consisting of a \(5 kΩ\) resistor and an LDR) and a \(5 V\) power supply. Use the information in the table to ...

The two resistors may have fixed values or one may be an LDR, a thermistor or other input ... way the resistors are connected together. The circuit of a voltage divider may be drawn with the ...

Build a light-activated switch using LDR that lets you control home appliances using your mobile phone's torch.
