Electricity Test Review

As is the case of unlike magnetic poles, unlike electric charges

• attract
• repel
• exist in pairs
• do not interact

The build up of charges on an object is called

• static discharge
• static electricity
• positive charge
• negative charge

Clothes in a dryer acquire static cling by

• friction
• conduction
• induction
• static charge

The loss of static electricity as electric charges move off an object is called

• friction
• conduction 
• induction
• static discharge

What causes charges to move in a circuit

• voltage
• energy
• electricity
• magnetism 

In a series circuit with 3 light bulbs, adding another bulb will

• make the nearest bulb brighter.
• make some of the bulbs dimmer.
• make all the bulbs brighter.
• make all the bulbs dimmer.

In a parallel circuit with 3 bulbs,

• the bulbs must all be located on the same path.
• there is only 1 path for the current to take.
• current for each bulb has its own path.
• resistance increases if a new path is added.

A complete, unbroken path through which electric charges can flow is a(n)

• electric circuit
• electrical resistance
• magnetic field
• electric field

Materials that allow the charge of an electric current to move freely through them are called

• insulators
• conductors
• resistors
• magnets

An example of an insulator is

• rubber
• copper
• silver
• iron
