Explain why the outside cases of electrical appliances are usually made of plastics?
Electrical appliances are made with plastic outer cases because plastic is a non-conductive and lightweight material that helps to reduce the risk of electrical shock. Additionally, plastic is durable, heat-resistant, and cost-effective, making it a suitable material for housing electrical components.

What is the difference in electrical charge between two regions on a nerve?
There is a slight difference in electrical charge between the inside and outside of a nerve cell membrane, known as the resting membrane potential. This potential is typically around -70 millivolts, with the inside of the cell more negative compared to the outside. This difference in charge is essential for the nerve cell to transmit electrical signals.
Does a motor have electrical energy in it?
An electric motor need to be supplied electricity to operate. It can be made to generate electricity if turned by an outside force when set up correctly.
What tree events of matter and energy that you cant explain?
I can't explain events that involve supernatural or paranormal occurrences. These include phenomena such as ghosts, telekinesis, or other unexplained events that fall outside the realm of scientific understanding.
Explain why the outside cases of electric appliances ususally are made of plastic?

What does electrical appliances use to keep temperature constant?

When the temperature rises or falls outside the set range, the thermostat signals the appliance to turn on or off to keep the temperature stable.
What is the purpose of the ground wire outside the house and how does it contribute to the safety of the electrical system?
The ground wire outside the house serves to provide a path for excess electrical current to safely flow into the ground. This helps prevent electrical shocks, fires, and damage to appliances by redirecting the current away from the electrical system. In essence, the ground wire acts as a safety measure to protect both people and property from potential electrical hazards.
Where is the outside breaker box located in relation to the main electrical panel?

What appliances have three pins and which have two pins?
Appliances and tool that only have two pin caps (plugs) are built so that they have double insulation. This means that the electrical "hot" parts can not be touched by handling the appliance or tools and the outside shell is completely insulated and isolated from the inside shell of the equipment. Equipment that require a three pin cap (plug) do not have the double insulation and isolation built into the equipment so protection from getting an electrical shock is done by grounding the equipment, that is what the third pin is. It is used strictly for grounding.
