C1-100

The definition of this is the ability

to do work.

C1-200C1-100

Power is the ratio of these two

physical quantities.

C1-300C1-100

When 100 Joules of energy go into an

electrical generator with 40% efficiency, this much

electrical energy comes out.

C1-400C1-100 This is the work done by a 100 Newton force

lifting an object 10 meters high.

C1-500

C1-100 This is the power rating on a toaster oven that uses 10

Amps of current at 120 Volts.

C2-100C1-100This device turns off automatically if

the current in an electrical circuit

gets to large.

C2-200C2-100C1-100C2-100C1-100 For safety reasons… some appliances have these special plugs to

minimize the chance of you getting shocked.

C2-100C1-100

C2-300

High powered appliances have this third plug, which is

called and eventually connects to this.

C2-400C2-100C2-100C1-100These are four of the eleven safety

checklist items suggested for the safe

use of electricity.

C2-500C2-400C2-100C2-100C1-100 This is why household circuits

are wired in parallel and not

series.

These are the names of three different sources of energy used to generate

electricity.

C3-200C2-400C2-100C3-100C2-400C2-100C2-100C1-100This is the name of the device that

converts mechanical energy into electrical

energy.

C3-300C2-400C2-100C3-100C2-400C2-100C2-100C1-100

This resource is the ultimate source of all

most every energy resource on the

Earth.

C3-400C2-400C2-100C3-100C2-400C2-100C2-100C1-100 Two major differences

between solar energy and Fossil

fuels are these.

C3-500C2-400C2-100C3-100C2-400C2-100C2-100C1-100 Scientists and environmentalists are

interested in the advancement of fuel cells because their

waste produces this.

C4-100C2-400C2-100

Power is the product of these

to electrical quantities.

The first player to buzz in wins 100 points and a piece

of candy.

C4-300C4-100C2-400C2-100

Transformers are used to do this before

electricity is transmitted from the generating station.

C4-400C4-100C2-400C2-100C4-300C4-100C2-400C2-100If all electrical wiring and circuitry were made from super conducting material

the efficiency of all electronics would do this.

C4-500C4-400C4-100C2-400C2-100A transformer is used to change convert electricity

from 100 Volts and 10 Amps into 1000 Volts and

this many Amps.
