The ground (earth if your Irish like me) is a protective conductor,in the event of a exposed conductive part of anything comes in contact with a current carrying conductor the earth dissipates the current to ground by a path of least resistance,ie a person would be harder to get through than a copper cable
If you touch an insulator with a conductor carrying electricity, there will be no electrical flow between them because the insulator does not conduct electricity. However, it's important to note that touching the conductor can still be dangerous as you may provide a pathway for the electricity to flow through your body to ground.
Glass is an insulator. That's why it's used to hold powerline conductors to the cross-bars of power poles. No current leaks to ground because the glass does not conduct electron flow (current).
A ruler is typically made of plastic, which is an insulator. This means it does not conduct electricity well.
Velcro is an insulator, meaning it does not conduct electricity. It is made up of nylon or polyester fibers which do not allow electricity to flow through them.
A magic one is an insulator.
The case of the TO-220 LM7805 regulator is device ground. If the heatsink is also ground, you do not need an insulator. If the heatsink is not ground, or if you need to maintain distinct grounds, or if the LM7805 ground is something else besides ground, you need an insulator. Its up to you, since you are responsible for system and circuit design.
Grounding a load typically involves connecting it directly to the ground through a conductor, not an insulator. This is done to provide a path for electrical current to flow safely to the ground in case of a fault or overload, protecting the equipment and preventing electric shock hazards. Using an insulator would prevent this purpose from being achieved effectively.
Yes. Used on top of metal lids in in ground cooking pits.
The insulator keeps the electrode in the center of the plug from contacting the engine block on the outside. if the insulator wasnt there, the plug would have no spark because all the coil energy would go straight to the ground on the circuit, the engine block
It is an insulator.
Snow acts as an insulator, trapping a layer of air between snowflakes that helps prevent heat from escaping the ground. This trapped air reduces heat transfer between the ground and the cold air above, insulating the ground and helping to keep it warmer.

Rubber is an insulator for normal voltages.
No, plastic is an insulator. If the ground pin were made of plastic then there would be no conductivity through the pin to conduct the fault current back to the distribution panel ground. It is this current path that trips the breaker on a ground fault.
