Safety Rules for Electricity

Back

• Never touch anything electrical with wet hands or while standing in water.

• Don’t overload electrical sockets.

• Pull a wire by the plug, not by the cord.

• Never go in a swimming pool when there is lightning.

• Don’t use frayed or broken cords.

• Don’t use a plug that is missing a prong.

• Don’t touch a light bulb after it has been on for a while.

• Never touch a downed power line or climb a utility pole.

What is the rule that should always be followed when connecting batteries?

Back

When connecting batteries, the rule that should always be followed is proper polarity.  This means that opposite terminals should always be connected.

Front

What is an insulator? What are some examples of an insulator?

Back

An insulator is material or objects that block the flow of electricity.

Examples of insulators are: plastic, wood, rubber, and chalk

Front

What is a conductor? What are some examples of conductors?

Back

A conductor is material or objects that allow the flow of electricity.

Examples of conductors are: copper wire, penny, humans, steel nail, aluminum paperclip

Front

What is an electric circuit?

Back

An electric circuit is the path that electricity follows.

Front

If you add batteries to a Series Circuit, will the bulb be brighter?

Back

YES! This is because there is only ONE path for the electricity to flow in a series circuit.  Therefore, the batteries work together providing more power to the bulb.

Front

What is the difference between a Series Circuit and a Parallel Circuit?

Back

In a Series Circuit, there is only ONE path for the flow of electricity or electrons to follow.  In a Parallel Circuit, there is MORE THAN ONE path for the flow of electricity or electrons to follow.

Front

If you add more batteries to a Parallel Circuit, will the bulb be brighter?

Back

NO! There is MORE THAN ONE path for the electricity to flow in a Parallel Circuit.  Therefore, each battery’s power has its own path to follow.  The batteries do not work together to provide more power to the bulb.

Front

In a Series Circuit, if you unscrew one bulb, will the circuit be broken?

Back

YES! In a Series Circuit, there is only ONE path for the electricity to flow. Therefore, when you unscrew the bulb the circuit is broken and the electricity will stop flowing.
