• repel each other

• do not interact.

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

• friction.

• conduction.

• static discharge.

Suppose you acquire a positive charge from walking across a carpet. You then touch a doorknob and receive a shock. This leaves you ....

An electric current will always follow

• the path of least resistance.

• a path toward the south pole. 

• the path that leads through insulators.

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

• conduction.

• current.

• potential.

In a series circuit with three bulbs, adding another bulb will

• make SOME of the bulbs dimmer.

• make ALL the bulbs brighter.

• make ALL the bulbs dimmer.
