Unit D Section 1.2 Flashcards
What is an electroplaque:
Special organ in a tail of an eel that produces electricity.
What is an Electrical Current:
The steady flow of charged particles.
Two requirements for electricity to flow:
- Energy source
- Complete path or circuit to flow through.
Amperage:
The rate at which an electrical current flows in a circuit.It is a measure of how many electrons move past a point in a circuit each second
Amperage Unit?
Measured by units ‘Amperes’ (A).
Voltage:
A measure of how much electrical energy each electron/charged particles carry.
Voltage Unit:
Measured in units called ‘volts’ (V).
Average amperage in the house:
Most electrical devices in our homes have an amperage of less than 15A.
the amperage of appliances?
60W Lightbulb= 0.5 A Microwave oven= 5-8A Clock radio= 0.4 A Television= 3-4.7 A Toaster= 8 A Toaster oven = 11 A Oven= 35 A Electric Kettle= 13 A Flashlights= 6 V Portable Stereo=6 V Home sockets= 120 V Cars = 12 V Machinery factories= 600V
Difference between conductors and insulators:
- Insulator- Material that currently does not flow easily through
- Conductors- Material that current does flow easily through
Conductor examples:
Silver Nickel Ruby Brass Tin Zinc Human body Aluminum Copper Iron Wool Tungsten Tap water (contained minerals) Heated glass
Insulator examples?
Air Wood Rubber Plastic Fur Porcelain/Ceramic Silk Carbon Distilled water (because it is pure). Glass (room temp)
What is a circuit?
A circuit is a complete path that controls electricity.
What are the four things that a circuit consists of?
Conductor
Energy source
Load
Switch
What is a load?
The load is a device to convert electrical energy to another form of energy.
Ex. , the light bulb is the load. It converts electrical energy to light and heat.
