Where do the wires connect on a light bulb?
Here’s the journey that energy takes to light up a bulb: Electrical current flows from the power box to the outlet which is contact with the plug. From the Hot/Narrow plug prong it flows to the Hot wire of the cord. The Hot wire is connected to the Hot terminal screw of the socket.
Does it matter which way a light bulb is wired?
If you wonder why you have to identify and connect the hot and neutral wires correctly in a lamp, read on. True, the lamp will usually work either way. But the issue is safety. Normally, power (voltage) comes through the tab on the socket base.
What is the wire in a light bulb called?
The thin wire present inside the light bulb is named as the filament of the bulb. It is made of tungsten. … Being a conductor, the current heats up the filament. This heat energy gets converted to light causing the bulb to light up.
What happens if live and neutral wires are the wrong way round on a plug?
If your outlet’s polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. … There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off.
Will LED lights work if wired backwards?
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.
