CIRCUIT- ELECTRICAL COMPONENTS SYMBOLS 61-9

Graphic Description

61
Diode
The diode is a semiconductor crystal, and its
role is to allow the current flowing to a fixed
direction.

Light Emitting Diode
A light emitting diode is a crystal diode, and its
role is to convert the power energy into light
energy.

Horn
Speaker is an electro-acoustic component, and
its role is to convert electrical signal into the
warning sound.
Speaker
It is an electro-acoustic component, and its role
is to convert electrical signal into sound waves.

Resistor
Is an electronic component, its function is to
divide voltage and the current limitation.
N resistors in series, and chang the resistance,
the current in the circuit can be changed, so as
to achieve the role of speed regulation. (High-
power status)
Sliding rheostat
By changing the length of the resistance wire
that access into the circuit to change the
resistance value that access into the circuit, and
achieve the role of controlling the circuit. (Low-
power state)
