Intro to electricity

The electricity we use was generated

• an hour ago

• milliseconds ago

• a few minutes ago (depending how far away the power station is.)

This is the type of current used in this country to power our homes and industries.

• indirect current

• direct current

• alternating current

• high voltage current

Electricity can be pushed over great distances if it is sent out in a very high voltage. We use this to step the current down to 120v for our houses.

• transformer

• transducer

• super conductor

• insulators

Electricity is put onto this to be delivered to the customers. There are only 4 in North America

• internet

• Power grid

• interweb

• power web

Electrons that are "plucked off" from other atoms and gather on an object is called

• Standing electricity

• Free electrons

• Static electricity

• Dynamic electricity

Because of its size and positive charge, electrons always want to go to

• Starbucks

• the next wire

• the negative end of a battery

• Ground

Electrons have the ability to do work

• True

• False

Electricity flows in a closed path called a

• conductor

• circuit

• current

A complete circuit MUST contain all of these things EXCEPT:

• Load

• Power supply

• Switch

• Conducto

A circuit that has a break in the wire is called a

• closed circuit

• series circuit

• open circuit

• parallel circuit
