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 ...

The circuit of a voltage divider may be drawn with the two resistors vertical, not horizontal. If there are two resistors in series across a voltage source, then the circuit is a voltage divider.

A resistor divider is commonly used for this purpose, reducing the high-voltage signal into a lower-voltage full-scale range. Figure 2 is a circuit diagram for DC bus measurement designed using ...

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 ...
