Science 9 Unit 4: Electricity Name:
... A circuit is a pathway that allows the flow of electricity. Most electrical circuits use wires (as conductors), although others may use gases, other fluids or materials. All circuit diagrams have four basic parts: 1. source - provides energy and a supply of electrons for the circuit (ex. Battery) 2. ...

TAP 115- 2: The filament lamp
... Instead of using an ammeter and voltmeter, connect a filament bulb in a lamp holder to the joulemeter which measures the power dissipated in the lamp. Reset the joulemeter if applicable. Select 0 V on your power supply. You will select different voltages each time. Warning: you must not exceed the v ...

Electrification
Electrification is the process of powering by electricity and is usually associated with changing over from another power source. The broad meaning of the term, such as in the history of technology and economic history, usually applies to a region or national economy. Broadly speaking, electrification was the build out of the electrical generating and distribution systems which occurred in Britain, the United States, and other countries from the mid-1880s until around 1950 and is in progress in rural areas in some developing countries. This included the change over from line shaft and belt drive using steam engines and water power to electric motors.The electrification of particular sectors of the economy is called by terms such as factory electrification, household electrification, rural electrification or railway electrification. It may also apply to changing industrial processes such as smelting, melting, separating or refining from coal or coke heating or chemical processes to some type of electric process such as electric arc furnace, electric induction or resistance heating or electrolysis or electrolytic separating.Electrification was called ""the greatest engineering achievement of the 20th Century"" by the National Academy of Engineering.
