Understanding Electrical Conductivity

Electrical conductivity measures how well a material allows electric charge movement, with its SI unit being Siemens per meter. Good conductors like metals allow electric current to pass easily, while insulators like rubber and wood do not. Conductors have higher electrical conductivity than insulators.

What is electrical conductivity a measure of?

• The temperature change in a conductor

• The speed of electric charge in a vacuum

• The ability of a material to accommodate electric charge

• The ability of a material to resist electric charge

What is the SI unit for electrical conductivity?

• Ohm per meter

• Ampere per meter

• Siemens per meter

• Volt per meter

Which of the following is a good conductor of electricity?

• Copper

• Wood

• Rubber

• Plastic

Which material is NOT a good conductor of electricity?

• Silver

• Plastic

• Aluminum

• Copper

What is the relationship between good conductors and electrical conductivity?

• Good conductors have the same electrical conductivity as insulators

• Good conductors do not conduct electricity

• Good conductors have higher electrical conductivity than insulators

• Good conductors have lower electrical conductivity than insulators
