when a light bulb is switched on it will blown..............
You throw it at the ground.
When the tail light and break light are on the same bulb said bulb has 2 elements, one for the break and the other for the tail light, one element is burned out. Replace the bulb. If you've replaced the bulb, it might be the wiring. The holder for the bulb sometimes is at fault. They are $40.00 at the dealer, but at a pick a part or salvage yard they are $2.00.
If you break a light bulb in its socket, isolate the power (turn off the electric to that socket). Then use a needle nose pliers to get out rest of it with lamp off
When a light bulb burns out it no longer makes light. This is because there is no way to connect the flow of electricity.
its being transferred
That means that the bulb looks bright.
Shouldn't it light?
If the voltage is appropriate, the bulb will shine.
Energy is dissipated as heat and light
the main reason for a light bulb to break is, the light bulb heats the tungstin wire. When the tungstin wire gets heated to much it breaks, causing thi light bulb to stop working.
The energy to produce the light stops and the light stops.
