• magnetic electricity.
• none of the above.

When you touch an object, if electrons jump from your finger to the object this jumping is called

• static electricity.
• current electricity.
• magnetic electricity.
• an electrostatic discharge.

When electric charges have a path to follow, this flow of charges is called

Two positive charges

• attract each other.

A material that resists the flow of electric charge is called

• a conductor.
• an insulator.
• a resistor.
