ELECTRICITY AND DIRECT CURRENT CIRCUITS
- Lorrein Zayrah Navarro y Kris Noelia Cong-o
CONDUCTORS AND INSULATORS
Conductors
: materials that let electric current flow through them.
Insulators
: materials that do not let electric current flow through them.
ELECTRIC CIRCUITS - COMPONENTS
Electric circuit
: is a series of interconnected components that an electric current flows through to produce an effect.
THE FOUR MAIN COMPONENTS
Load devices
: Components that recieve the electrical energy from the power sources and convert it to the other types of useful energy.
LAMP
MOTOR
BUZZER
RESISTOR
Power sources
: Components that supply the necessary electrical energy. The generators of direct current in a circuit are cells and batteries
BATTERY
CELL
Control devices
: Devices that regulate the circuit in other words, they allow or prevent the flow of current through the circuit.
ONE-WAY SWITCH
PUSH SWITCH
TWO-WAY SWITCH
Conductors
:Components that transport the electrical energy from the power sources to the load devices;in other words, the electric curret flows through these components.
WIRE
Electrical schematics
We represent electrical circuits with a very simple drawing are called
electrical schematic
. Every component in a circuit has a
standardised symbol
to represent it in a simple way that anybody can understand.
EXAMPLES OF REPRESENTATIONS OF CIRCUITS
electrical energy
presentation of an atom
electric current
:is the flow of electrons from one atom to another
MOVEMENT OF ELECTRONS
electrons
:negative charge
neutrons
:neutral charge
protons
:positive charge
electricity
:is a form of anergy thar lets negatives charge particles move from one atom to another
