Electric Lab 700
The
PERT INDUSTRIALS Electric Lab is a complete system for teaching
basic electricity and electronics.
Just plug the unit into the mains, open the first page of the manual and get ready to get wired!
Experiments
The following experiments, inter alia, can be performed using the Electric Lab:
Electricity
through heat - Electricity by magnets - Cells - AC and DC Power - Loads in series
and parallel - Voltage - Current - Ohms law - Power - Heating effect & the
fuse - Magnetism - Magnetic field - Magnetic properties - Magnetic Strength
- Field around a conductor - Magnetic field about an helix - Electromagnetic
strength - electromagnetic effect and the coil - The relay - Meter Movement
- Voltmeters and Ammeters - Meters in circuit - Short circuits - Resistors in
Parallel Kirchhoff's laws - Applying Ohms law - Lenz's Law - Self Inductance
- Mutual Inductance - Transformer Action - Voltage/turns ratios - Reluctance
- Capacitors in series - Capacitors in Parallel - Charging of Capacitors in
series - Charging of capacitors in Parallel - Discharging of capacitors - RC
Circuits - The diode - The diode rectifier - The AND and OR truth table - The
exclusive OR - Motor Action - Motors and Generators - The DC Generator - The
series Motor - The Shunt Motor - Reversal of Rotation - The AC Generator - The
universal Motor.
The Electrolab Method
The
electrolab course starts at the very beginning with the various methods
of producing electricity, heat, magnetism and chemical action. The student
then investigates a range of electomagnetic charactersitics and properties
before advancing to components and instruments. At this stage the student
is more concerned with the components and making up the circuit rather than
the circuit itself. As he gets more accustomed to the effects of electricity
and the properties of electronic components, he learns how to combine and
integrate these to produce useful results.
The
Electrolab Construction
Components are large and easily identified; everyday items are used when possible, a resistor looks like a resistance wire and not like a little tube with thousands of ohms of resistance, a pushbutton looks like its description...
Expense has not been spared: five meters have been
provided instead of a single multimeter, a galvanometer shows what
happens when a magnet moves inside a coil and if you put heat to the thermocouple
it "magically" causes a current flow.
The
cost to performance ratio has been enhanced by the multifunctional choice of
components: E.g. The electromagnet is used to demonstrate Electromagnetism,
Transformer action, Lenz's Law, Motor action and doubles up as the field coil
of an electric motor.
