Question: Is a measure of the ability of a material to conduct electric current?

What device measures the ability of a material to conduct an electrical current?

ammeter: An instrument used to measure the electric current in a circuit; the unit of measurement is amperes or amps (A). circuit: A path for electric current to flow. conductor: A substance made up of atoms which hold electrons loosely, allowing them to move through it more easily.

What are 5 good conductors?


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

Which metal is the best conductor of electricity?

What Metal is the Best Conductor of Electricity?

  • Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. …
  • Copper. One of the most commonly used metals to conduct electricity is copper. …
  • Aluminum.

What material is used in order for electricity to flow?

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.

Which material is not good conductor?

Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.

GOOD TO KNOW:  Question: Which consumes more electricity front load or top load washing machine?

How do you measure voltage and current?

Measuring current and voltage

  1. Current is measured in amperes. Amperes is often abbreviated to amps or A. The current flowing through a component in a circuit is measured using an ammeter. …
  2. Voltage is measured in volts, often abbreviated to V.
  3. The voltmeter must be connected in parallel with the component.
