Introducing Current Electricity Electric
Circuit a continuous path in which electrons
flow Source a supplier of energized
electrons -either a battery or from a wall
outlet LG to understand the basics of
current electricity

Introducing Current Electricity Electric
Circuit a continuous path in which electrons
flow Load a device that converts electrical
energy into other forms of energy -e.g. lamp
or motor LG to understand the basics of
current electricity
6
Introducing Current Electricity Electric
Circuit a continuous path in which electrons
flow Conductors wires that transmit electrons
from the source anode (negative terminal) to the
load back to the source cathode (positive
terminal) LG to understand the basics of
current electricity

Introducing Current Electricity Electric
Circuit a continuous path in which electrons
flow Switch a device that controls the flow of
electrons by opening the circuit open
closed LG to understand the basics of
current electricity

Introducing Current Electricity Electrical
Energy the energy provided by the flow of
electrons in an electric circuit Electric Cell
a device that converts chemical energy into
electrical energy Batteries can contain one or
many cells Primary Cell an electric cell that
can be used only once Secondary Cell an
electric cell that can be recharged LG to

Introducing Current Electricity Forms of Current
Electricity Direct Current a flow of electrons
in one direction through an electric
circuit -form produced by batteries LG

13
Introducing Current Electricity Forms of Current
Electricity Alternating Current a flow of
electrons that alternates in direction in an
electric circuit -produced in generating
stations because it's more efficient at
distributing electricity long distances L
