In this installment of Circuit VR, we’ll look at a simple buck converter — that ... size — but probably not all of them at once. For example, adding a snubber has advantages, but will ...

For simple circuits, it’s easy enough to grab a breadboard and start putting it together. Breadboards make it easy to check your circuit for mistakes before soldering together a finished product.

A buzzer. This is a simple output device that makes a sound once the circuit is complete and current is passing through it.An LED or light emitting diode. This is another example of a simple ...

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.
