Electricity and Magnetism

The buildup of charges on an object is called

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

According to Ohm’s law, resistance is equal to voltage divided by

• time
• conduction
• current
• potential

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

• electric circuit
• electrical resistance
• magnetic field line
• magnetic pole

Materials through which charge can flow easily are called

• insulators
• resistors
• conductors
• magnets

An example of an insulator is

• rubber
• copper
• silver
• iron
