How did the light bulb affect the environment?
They also burden the environment due to their wasteful energy consumption. A typical 100-watt incandescent bulb uses 75% more energy than an equivalent CFL and 80% more than its LED equivalent. This energy increases utility costs and is responsible for creating higher levels of greenhouse gas emissions.
What’s positive and negative on a light bulb?
The positive is where the positive charge carriers come out, full of ELECTRIC POTENTIAL ENERGY and the negative is where they come back in, after doing their “work”, to get re-energized by the battery. Now look at your bulb – it has two terminals also, but they are a bit hidden.
Does positive and negative matter for a light bulb?
Light Bulbs – With some appliances, polarity doesn’t matter. When you screw a light bulb into a socket, the electricity is intended to flow into the light bulb from the button on the bottom of the socket.

What happens if you connect positive and negative together?
Connecting one battery positive terminal to the other’s negative will cause a great surge of electric current between them.
