but it’s a useful safety feature in some electric tools like lawn mowers. They have two switches that both need to be held closed to complete the series circuit, before the lawnmower will work.

It's wires that connect to different electrical components, like a light bulb, a switch, and a battery. JAMES: Yeah, there are actually two types of circuits. We have series circuits and parallel ...

In a series circuit, the current passes from the power ... After the two parts are combined, each light is tested again for electric charge. Then the machine covers the metal piece in between ...
