Question 15

Does a neutral object contain electric charge?

Answer 15

Yes, positive and negative charges are present but balance each other making it neutral

Question 16

Do neutral charged objects, attract to positive and negative charges?

Answer 16

Any charged object, whether positively charged or negatively charged will have an attractive interaction with a neutral object

Question 17

How is a filament (Tungsten) in a globe responsible for producing light

Answer 17

When you pass electric current to a filament it will glow

Question 18

What is the difference between current and voltage?

Answer 18

Current is the rate at which electric charge flows past a point in a circuit. Voltage is the electrical force that would drive an electric current between two points.

Question 19

What is an electrical insulator?

Answer 19

Electrical insulators don’t conduct electricity as it has a lot of resistance to the flow of current
