Troubleshooters Library. This lesson uses animation to demonstrate
atomic structure, electricity, and how a simple circuit operates. The
lesson also explains the characteristics of good conductors and
insulators.
Modules:
Module Name: Introduction to Electricity
Basic Electrical Properties
This is the second lesson in the iKNOW™ Electrical Theory for
Troubleshooters Library. This lesson covers Ohm’s Law and the use of
Ohm’s Law to calculate an unknown value. It also defines voltage,
current, resistance, and power.
Modules:
Module Name: Basic Electrical Properties
Series Circuits
This is the third lesson in the iKNOW™ Electrical Theory for
Troubleshooters Library. The lesson presents the operation of a series
circuit and trains participants in the identification of simple
schematic symbols used to represent components in a series circuit. The
behavior of current, resistance, and current in a series circuit, and
the used of Kirchhoff’s Voltage Law to find total voltage are also
covered.
