What kind of circuit is this?

• series
• parallel

What kind of circuit is this?

• Series
• Consecutive
• Parallel
• Training

An example of a parallel circuit is

• the wiring in a house
• a flashlight
• a single circular path

How many Volts would it take to push 1 Amp through a resistance of 1 Ohm

• 10 volts
• 1 volt
• 48 volts
• 5 volts

Which value best represents the resistance of a toaster that draws 12 amps of electricity on a 120 volt line?

• 0.1 Ohms

• 132 Ohms

• 10 Ohms

• 1440 Ohms

The values shown in the table are a measure of how much current will flow in a standard sample of metal. Which metal is the best conductor?

• Aluminum

• Silver

• Iron

• Copper

If you cut a magnet in half, what happens to the poles?

• One half gets the North Pole, the other half gets the South Pole
• Both halves get only a North Pole
• Both halves get only a South Pole
• Both halves get a North pole and a South Pole

motors and generators could not operate with out magnetism.

• True

• False

An electromagnet can be made stronger by:

• increasing the number of turns in the coil

• putting a piece of soft iron in the core

• increasing the current through the coil

• any or all of the above

As a magnet is moved closer to a piece of

magnetic material, the force of attraction:

• does not change

• changes linearly

• changes with the inverse square of

  
  

  distance

• reaches saturation
