,Components Summary
Cell A cell provides a source of
electrical energy. A battery
symbol is made up of two or
more cells
Battery A battery is a source of energy
which provides a voltage of
energy to get the current flowing
in a circuit. A bulb uses the
electrical energy provided by
the battery, but does not use
current. When the energy in the
battery is used up there is no
current and the bulb does not
light up
Switch A switch is an electrical
component that can disconnect
or connect the conducting path
in an electrical circuit,
interrupting the electric current
or diverting it from one
conductor to another
Filament Lamp A filament lamp is a common
type of light bulb. It contains a
thin coil of wire called the
filament. This heats up when an
electric current passes through
it, and produces light as a
result.
Fixed Resistor Fixed value resistors have a
defined ohmic resistance and
are not adjustable. Fixed
resistors are the most
commonly used resistors and in
general one of the most used
, electronic components
Thermistor The Thermistor is a solid state
temperature sensing device
which acts a bit like an electrical
resistor but is temperature
sensitive.
LED ( Light Emitting Diode) It is a semiconductor light
source that emits light when
current flows through it.
LDR( Light Dependent Resistor) LDR is a component that has a
(variable) resistance that
changes with the light intensity
that falls upon it. This allows
them to be used in light sensing
circuits.
Rheostat adjustable resistor used in
applications that require the
adjustment of current or the
varying of resistance in an
electric circuit
Capacitor is a passive two-terminal
electrical component used to
store energy electrostatically in
an electric field. A capacitor
stores energy in the form of an
electrostatic field between its
plates.
Voltmeter It is an instrument used for
measuring electrical potential
difference between two points in
an electric circuit
Ammeter is a measuring device used to
measure the electric current in a
circuit.
