Do all light fixtures have a ground wire?

What if the box has no ground wire?

What if there is no ground wire in light switch?
The plug without a ground cable is dangerous because there is no alternative path for the charge to escape from the circuit. As a result, the conducting area is under the voltage. You then run the risk of coming into contact with the deadly excess charges that emit from power outlets.
Can I leave ground wire exposed?
Grounding wires, especially those running through grounding rods on the exterior of your home, are exposed. The grounding wires are safe to touch unless there is an electrical surge that causes electricity to flow through the grounding wire.
