5D10.15 - Resistors - Characteristics of Tapered Resistors

Code Number:
Demo Title:
Resistors - Characteristics of Tapered Resistors
Principles and Varieties of Resistors
Area of Study:
Electricity & Magnetism
Voltmeter, tapered resistors (the tapered resistors we use are from old Duracell batteries).

Lay the tapered resistor on the table with the resistor side up.  Measure at different points of the resistor to show an increasing resistance with a widening of the resistance strip.
