Applications
Temperature was one of the first physical parameters to
be measured in the process field and has been sensed in
just about every way imaginable over the years. At one

ELECTRIC CIRCUITS AND CURRENT
The outstanding characteristics of electricity when compared with
other power sources are its mobility and flexibility. Electrical energy
can be moved to any point along a couple of wires and depending on

1.
"Discrete Math" is not the name of a branch of mathematics, like number theory, algebra, calculus, etc.
Rather, it's a description of a set of branches of math that all have in common the feature that they are
"discrete" rather than "continuous".

LASER ALARM
INTRODUCTION
Have you ever thought about implementing your own home security alarm
systems? Its one of the simplest and interesting circuits for electronic beginners.
This project proposal namely Laser Alarm is typically an alarm triggered by
Eriknicheskis Notes in EDEs
Differential equations are formed by eliminating arbitrary constants. There are two
types of constants in mathematics, absolute constant and arbitrary constant. The latter is
defined as constant which has fixed value for partic
Bipolar Transistor Basics
Transistors are three terminal active devices made from different semiconductor materials
that can act as either an insulator or a conductor by the application of a small signal
voltage. The transistors ability to change between
