• Light, heat, magnetic

According to the conservation of energy, energy can be:

• Created from nothing

• Destroyed completely

• Transferred or transformed

• Static and unchangeable

What happens when charged objects are brought close to each other?

• They exchange energy

• They attract or repel

• They become neutral

• They create light

What is necessary to carry an electric current ?

• A light bulb

• A resistor

What occurs in a series circuit when another bulb 'blows'?

• The remaining bulbs get brighter

• The circuit breaks and all bulbs go out

• The current doubles

• Nothing happens

How does adding more bulbs in series affect the brightness of the bulbs?

• Increases brightness

• Decreases brightness

• No change in brightness

• Randomly changes brightness

In a parallel circuit, what is unique about the paths the current can take?

• Current can only take one path

• Current can take multiple paths, each called a branch

• Current reverses direction in each path

• Current flows intermittently in each path

What happens to the current in a parallel circuit when one of the bulbs 'blows'?
