Question 1

What happens when you rub two insulators together

Answer 1

You can transfer electrons from one insulator to the other. One object ends up with less electrons than protons and one ends up with more protons than electrons.

Question 2

What is the charge on an object called

Answer 2

Static charge

Question 3

How do you discharge an object

Answer 3

You can remove the charge by connecting it to something that allows charge to flow

Question 4

What is around a charged object

Answer 4

There is an electric field around a charged object or particle. If you put another charged object in this field it will be attracted or repelled even if the objects aren’t touching.

Question 5

What is current

Answer 5

Current is the rate of flow of charged particles or charge.

Question 6

What do you need to make current flow

Answer 6

A cell or a battery

Question 7

Which way does conventional current grow (how you should draw it)

Answer 7

It goes from the positive side of the battery to the negative side of the battery. This is opposite to the electron flow.

Question 8

Equation for charge flow

Answer 8

Charge flow (Coulombs) = Current (A) x time (s)

Question 9

what direction do the arrows go in a charge diagram

Answer 9

go to the negative charge and away from the positive charge
