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 ...

There is another family of transistors which have analogous circuit configurations to their bipolar cousins but work in a completely different way: the Field Effect Transistors, or FETs.

The camera is triggered by any readily available Bluetooth dongle, which is connected via a simple transistor circuit to an Arduino output. To trigger the shutter, a light-dependent resistor (LDR ...
