 The
unit used to measure
the electrical current or
flow of electrons through
an electrical conductor or
circuit.
A
source of electrical
energy that is created by
a chemical reaction and
pushes electric charges
within a circuit.
 The
connecting points or
locations on a battery
where the electrical
charges leave or enter
the battery.
A
path through which
electricity flows
A
complete electrical
circuit or path through
which electricity or
current can pass or flow
 Materials
through which
electrical current can flow.
Copper is a good
conductor. Most electrical
wires are made of copper.
A
flow of electrons; the
quantity of electrons
that moves through a
circuit. Electric current is
measured in amps.
A
device that changes
or converts
mechanical energy
into electrical energy.
A
device that converts
or changes electrical
energy into
mechanical energy.
 Materials
that do not easily
carry or allow the passage
or flow of an electric
current. Examples are glass,
rubber, plastic, and air.
 The
unit used to measure
the resistance to the flow
of electrons or electric
current.
A
circuit or electrical path
that is broken or
incomplete , and so
electricity cannot flow
through it.

An electrical circuit in which the
electricity can follow more than one
path. It is a circuit that connects
several objects or resistances in a way
that allows each resistance to have its
own path. This is the way appliances
and lights are connected in homes, so
they do not all have to be on at once.
A
measure of how well
electricity moves through a
material. Insulators have high
resistance; conductors have
low resistance. Resistance of
an object is measured in
ohms.
A
circuit in which all the lights or
resistors are connected in
sequence, or one after the other,
forming a single path Through
which the electricity can flow.
Batteries in a flashlight and small,
portable radios are frequently
connected in series.
 Electricity
that is motionless
or at rest; it is produced by
rubbing two objects
together, such as a resin
rod and a piece of silk
fabric, or a balloon against
a piece of wool fabric.
A
device that allows an
electrical circuit to be
opened or closed.
 The
force or push, given by
a battery or generator that
moves electrons from one
place to another in an
electric circuit or conductor.
The
unit used to
measure voltage.
A
unit for measuring
how quickly or how
much an appliance or
other device uses
electricity.
