And when you work with one, you have to know that any part of the circuit can be at mains voltage. Now read on to see why! A transformerless power supply (TPS) is basically just a voltage divider ...

Potential dividers are commonly found in everyday devices like radios, games, and toys. For instance, if you have a 9V battery but need 6V for a part of your circuit, you can use a potential ...

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