Table based Electronics or Rb Technology

 At books in the future:

Rb = 4.3/Ib

Rb = 11.3/Ib

Lets check and Learn to design Rb at Fire Alarm:

Lets design the Control Panel, Inside and Out.

Remote LED Indicator = 2.2 volts

by table:

12v 1k 2.2v(led)

6v 500ohms(led)

5v 330ohms(led)

By table, Rb = 100 Ohms..

Hfe = Beta/10

Hfe, use multimeter function NPN cbe or bce

Beta = 300

Ic = Vcc/Rc = Beta x Ib

+24-IbRb-0.7 = 0

Rb = 23.3/Ib

from Vcc/Rc = Beta x Ib

24/400/300=Ib

Ib = 0.0002A

Rb = 116.500 ohms

Rb = 100 Ohms, OK (lesser) 

NOTE: add latch for Alarm Bell

Thats it!

THEORY OF ELECTRONICS

 Lets start with V = IR formula, Lets discover derivation of formula.

Current flow reading means you need to start reading from positive to negative while Electron Flow follows the transfer of valence electrons from atom to another so, negative to positive reading is being used. An absence of electrons means -1 net charge or negative ion and vice-versa for positive ion.

                                            Current Flow

Electron Flow

Derivation of Ohms Law or V= IR

Here we'll be using Kirchoff's Voltage Law or KVL using Current Flow

1. Draw the circuit and put + and - signs for voltages and resistances.

2. Read the summation of Voltages and equate to Zero using Current Flow:

+V - Vr = 0, since Vr = I x R

+V - IR = 0

Therefore, V = IR...

THATS it!!!

Code Base Electronics (CB)

Electronics changed the way we get through life. Listening to music and watching shows through computers is one of the greatest accomplishment of this era of Electronics. It gives us oppurtunity to get social, buy goods, read books, search for information and even what you call "everything".

 CB = Code Base

Topics:

CB zero = no computer electronics

CB one = computer control electrical/electronics

CB two = alarms

CB three = TI 74ls- series IC

Is Analog Digital?

According to CodeBase Electronics, Analog means many Digital. A Digital is a binary signals of bit and bytes of information (1 or 0) that corresponds to a word like the table data below:

Binary Information e.g. pwm (pulse width modulation)

01010101 A

00001111 B

11110000 C
