Lesson about resistor, how to read its values, 4 band to six bands

1. WHAT IS A RESISTOR?
A resistor is an electrical component that
limits or regulates the flow of electrical
current in an electronic
circuit. Resistors can also be used to
provide a specific voltage for an active
device such as a transistor.

2. DIFFERENT TYPES OF
RESISTORS
Wire wound Resistors
Metal film Resistor
Thick film and Thin film Resistors
Surface mount Resistors
Network Resistors
Variable Resistors
Light-dependent Resistors
