An LED must be connected in a circuit the right way around – observe the polarity of the LED. The way … WebIn electronics, polarity indicates whether a circuit component is symmetric or not. LEDs, being diodes, will only allow current to flow in one direction. And when there's no current-flow, there's no light. Luckily, this also means that you can't break an LED by plugging it in backwards. Rather, it just won't work. premier shine car wash berlin nj
