Electricity and magnetism Concepts revision mega game

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

• increases 
• decreases 
• stays the same 

Every magnet, regardless of its shape, has two.....

• magnetic poles.
• magnetic fields.
• magnetic charges
• magnetic needles

Magnetic poles that are unlike......

• attract each other.
• repel each other.
• do not interact.
• point in the same direction.
