Kids love building electric circuits, but connecting light bulbs to batteries with fiddly wires is tricky for young hands. Play dough and light-emitting diodes (LEDs) solve the problem beautifully.

Connecting them at only one point. Cutting the ground plane under a mixed signal component Connecting them with capacitors. Segmenting the ground plane in a PCB such that there is only a narrow ...

The Squishy Circuits team developed this activity so that young children (including my own daughters) would have a playful way to explore circuits. Squishy Circuits use two different types of dough as ...

The savings from multiwire branch circuits can come at a high cost. It's true that multiwire branch circuits reduce raceway size, voltage drop, and the number of conductors. However, mishandling or ...

Electrical system designers have at their disposal several types of fire resistive systems that comply with specific Code requirements. It can be helpful to ...

But, it turns out, a thermometer has been part of photonic chips all along.
