Which of the following is least likely to allow electricity to flow?

Materials that do not allow electricity to pass easily through them are called insulators. Rubber, glass, plastic, and cloth are poor conductors of electricity. This is why electrical wires are covered in rubber, plastic, or cloth.

What can electricity flow through?

The flow of electricity is called current. Metals are generally very good conductors, meaning they let current flow easily. Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.

What type of electricity does not flow?

Static electricity happens when electrons build-up on an object, but can’t flow any further, which creates an electric charge. This charge is released as static electricity if the charged object is touched by another object that can conduct electricity.

Which of the following would make the best insulator against the flow of electricity?

Glass, ceramic, wood, plastic, and rubber are all good insulators. Glass or ceramic are often used atop power poles to hold the power lines. Plastic is the typical coating for electric cords on electrical devices.

Do insulators allow electricity to flow through them?

Some materials do not allow electricity to pass through them. These materials are known as electrical insulators. Plastic, wood, glass and rubber are good electrical insulators.

GOOD TO KNOW:  Best answer: Are solar panels expensive to maintain?

What are 5 good conductors?

Conductors:

  • silver.
  • copper.
  • gold.
  • aluminum.
  • iron.
  • steel.
  • brass.
  • bronze.

Which is a path that allows electricity to continuously flow?

circuit: A path for electric current to flow.

What type of materials are resistant to the flow of electricity?

Materials that have high resistance to electric current are called electric insulators. Examples include most nonmetallic solids, such as wood, rubber, and plastic. Their atoms hold onto their electrons tightly, so electric current cannot flow freely through them. Dry air is also an electric insulator.

Why does electricity not go through rubber?

Rubber is known to be an insulator because rubber can limit the transfer of electricity. The rubber properties prevent the electrons to be able to freely move and the addition of the electrons being tightly bounded makes rubber a good insulator . Rubber itself usually cannot conduct electricity without any assistance.

Can current flow without a source?

Voltage is the Cause, Current is the Effect

Voltage attempts to make a current flow, and current will flow if the circuit is complete. … It is possible to have voltage without current, but current cannot flow without voltage.
