ELECTRICYTY AND DIRECT CURRENT CIRCUITS
BY:Gabriel Delgado
and
Héctor Zaragoza
Electricity is form of energy
Atoms:all materials are made up of very small particles.
Positive Change
Negative Charge
Neutral Change
Components of circuit
Battery:A group set of cells.
Cell:have a positive terminal and negative terminal.
Conductors and Insulators
Insulators:Material that does not let electric current flow through it.
Conductor:material that lets electric current flow through it.
Iron
Paper
Electric circuit:is a series of interconnected components that an electric current flows through to producean effect.
Load device:component that receives the electrical energy from the power source and converts it to other types of useful energy.
Conductors:component that transports the electrical.
Control devices:decives that regulates the circuit allowing or preveting the flow of electric current through the circuit.
Power Sources:component electrical energy to the rest of the cicuit.
Load devices
Buzzer:converts electrical energy to sound.
Lamp:converts the electrical energy to light.
Motor:converts electrical energy to kinetic.
Resistor:Convert electrical energy to heat.
Main electric
Voltage:difference in electrical energy between two points.Its unit of measurement in the international System is the Volt(V).
Current:intensity amount of electrons flowing through a conductor.Its unit of measurement in the international System is the ampere or amp(A).
Resistence:Opposition to the flow of the electric curent..Its unit of measurement in the international System is the Omh.(
)
Omh´s law:to calculate it easy we can do this.to calculate "R" you have to divide "V: I", to calculate "I" you have to divide "V: R" and to calculate "V" you have to multiply "R. I"
Energy and environment
Joule effect:phenomenon where heat is produced as electrons move through a conductor or load device.
Environmental impact:effects that use of energy has on the environment.
Responsability use the electrical energy,we can do this to take care.
Unplug unused electrical devices.
Take advantage of natural lighting.
Turn off the lights without using.
