CLASS POOL KIT
-
Description
This ‘one per class’ kit is designed
to give you a flexible suite of parts
that can be added to the Electrical
and electronic principles pack
to allow a much wider range of
experiments and demonstrations
in Electronics, from Operational
Amplifiers, PICmicro, Logic
and Energy and Environment
solutions. The pack also includes
useful equipment for teaching
Lenz’s law, Faraday’s law and motor
principles. This pack is suitable
for Physics extension work and
projects. The CD ROM supplied
includes workbooks in Energy
and Environment, PICmicro
investigations, Operational
amplifiers and working with logic
gates.
EXAMPLE OF USEOPERATIONAL AMPLIFIER – High gain differential amplifier
Operational amplifier is one fundamental building block of
analog circuits. When used properly in negative feedback
configurations, the overall closed-loop transfer charecterstics
can be precisely set by stable passive components such as
resistors, capacitors, and diodes, regarless of the potential
variation of open-loop parameters. Negative feedback
amplifier with op amp operating as its core provides key to
highly reliable and stable analog functions.A circuit similar to above can be built using the kit and the
students can start to experiment and test around with voltage at
different nodes and across difereent resistors to verify the current
and voltage laws.
