SNC1P Exam Review #3 (Electricity)

True or False: A negative charge will attract other negative charges

• True

• False

When an object loses electrons it becomes:

• Positively charged

• Negatively charged

When an object gains electrons it becomes:

• Negatively charged

• Positively charged

When a switch is open (like in the picture above), will electricity be able to run through it?

• Yes

• No

If the switch is closed (like in the picture above), will electricity will run through the circuit and power the light bulb?

• Yes

• No

What kind of electroscope is show in the picture above?

• Metal leaf electroscope

• Sciencey thingy electroscope

• Pith ball electroscope

• Hanging ball electroscope

Which one of the following objects has a neutral charge:

• An object with 3 protons and 2 electrons

• An object with 2 electrons and 3 protons

• An object with 3 electrons and 3 protons

• An object with 1 proton and 0 electrons

In order to 'ground' a charge, you need to give electrons a path to the Earth (ground) through a:

• Conductor

• Insulator

Why is there plastic around copper wires (as shown in the picture above)?

• The plastic insulates the electricity

• The plastic conducts electricity

• Because it looks cool

• You've confused me again Mr. Bulger...

Charging a neutral object by bringing another charged object close to, but not touching the neutral object is called:

• Friction

• Induction

• Conduction
