The two types known are:
1. Fixed capacitor
2. Variable capacitor under fixed we have
a) Electrolytic capacitor (polarized)
b) Non-electrolytic capacitor (non polarized)
CIRCUIT CONNECTION
A capacitor can be connected either in series or in
parallel. When connected in series, the equivalent
connection is this CT = 1 + 1 + 1 + 1 + 1 ------------- 1
CT C1 C2 C3 C4 Cn
When connected in parallel, the equivalent connection is thus:
CT = C1 + C2 + C3 + C4 ------------------------------Cn.
The S1 unit is farads “Fâ€.

RESISTOR
This is the most commonest component found in an electronics circuit.
It
is a device that offers opposition to the flow of electric current. The
amount of opposition depends on the ohmic value of the resistor.
TYPES OF RESISTOR
Just like capacitors, we have types of resistors
1. Fixed resistors
2. Variable resistors.
Both fixed and variable have no polarity, it can be connected in either way round.
CIRCUIT CONNECTION
It can be connected in either series or parallel. When connected in series the equivalent connection is thus:
RT = R1 + R2 + R3 + R4 -------------------------- Rn
While when connected in parallel, the equivalent connection is thus:
RT = 1/R1 + 1/R2 + 1/R3 + 1/R4 --------- 1/Rn

ABSRACT - [ Total Page(s): 1 ]This design implementation of this electronic sequential sign post display employs the use of some specialized components. This section of the project introduces the reader to the different section of the project and the components that makes them up.Emphasis are laid on describing the behaviour and operational system of the components as related to the project modeling, analysis, design and implementation of an ELECTRONIC SIGN POST, which is made up of a power supply, a shift register, a counte ...
