Is lead polar
WitrynaPolarity is a very important concept, especially when it comes to physically building circuits. Whether you're plugging parts into a breadboard, soldering them to a PCB, or sewing them into an e-textile project, it's critical to be able to identify polarized components and to connect them in the correct direction. WitrynaAll modern pacemakers can electronically detect external conductor errors and switch to uni-polar pacing to maintain rhythm until the lead is replaced. Figure : Lead …
