When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in series ...

Many LEDs, those highly popular Light Emitting Diodes, die prematurely because they are improperly used by people who know little to nothing about electronics. Let's try to stop the massacre. An LED ...

Knowing how to calculate an LED current limiting resistor is one thing, taking into account all other sorts of parameters as well is another. In Part 1 you learned how to calculate a current limiting ...

In Resistor combinations: How many values using 1kohm resistors?, Glen Chenier showed us how many combinations of resistor combinations you can get. Many people commented, trying to develop a formula ...

For example, often lawnmowers have two switches in series with each other so that both switches need to be pressed before the mower will turn on. The power ring circuit is also a parallel circuit. In ...
