PPT-More Resistors Activity 6.2.3a

2011 Project Lead The Way Inc Magic of Electrons Variable Resistors Potentiometers Variable Resistors A resistor whose value can be varied mechanically between its minimum and maximum values. Thats why TT electronics resistors have kept circuits safe for more than 70 years and why TT electronics continues to o64256er the industrys most comprehensive range of circuit protection resistors In addition to o64256ering standard components TT e 64 A Two-Digit Number Code is assigned to each standard Resistance Value per E96 guidelines. See chart below. The two-digit code is followed by a letter multiplier.

A resistor, like batteries and lights, can also be present in an electrical circuit. A resistor limits the flow of electricity in the circuit. Like rocks in a pipe that slow the flow of water, a resistor will limit the flow of electricity. A variable resistor is made of a piece of metal that can change in length. As the length of the resistor changes, so does the resistance in the same direction. .
