Electricity and direct current
electricity : form of energy
Electric current: flow of electrons
Movement of electrons
Electron forced out of its orbit
open circuits and closed circuts
a circut is OPEN when the energy of the power source cannot flow.
And a circut is CLOSED when the energy of the powersource reaches the load devices.
off , on.
Electrical energy:
light
heat
sound
motion
CONDUCTOR AND INSULATOR
Conductors
gold
silver
Aluminium
copper
ELECTRIC CIRCUITS. COMPONENTS
Electric circuit
Condctors: Transport the electrical energy
Load devices: recive electrical energy : LAMPS, OTORS, BUZZERS and RESISTORS
Power sources:cells and bateries
Control devices: Regulate the circuits
COMPONENTS OF A CIRCUIT
CELL
BATTERY
Load devices
lamp
motor
buzzer
resistor
converting electrical energy

TYPES OF CIRCUITS:
SERIES CIRCUTS
THE SAME CURRENT FLOWS THROUGHT ALL THE LOAD DEVICES
PARALLEL CIRCUITS
PARALLEL CIRCUIT:
Insulators
plastic
cardboard
wood
