Design. Engineering. Value. Interest. Creativity. Encyclopedia.
D.E.V.I.C.E. is an encyclopedia of terms used by manufacturers of test and measurement equipment. T&M Atlantic created this service to better explain the functionality of instruments it offers, and to highlight the latest developments in the world of measurement equipment. We are using such tools as animation to bring words and pictures to life and to create not just an understanding but also an appreciation for technology that goes into the design of every instrument.

When the relay closes and opens, its contacts can be damaged by the resulting electric discharge arc. To protect them, you can use RC chains installed in parallel with the relay or load. You can calculate the parameters of the elements needed for this here by entering the general characteristics of the circuit.
A helpful tool for reading resistor color code values for a 4 and 5 band resistor. This tool allows you to determine resistance by resistor color coding and to determine resistor color coding by resistance. It displays Rated resistance, Resistor tolerance, Resistor length and Resistor power all in one easy to read chart.
This tool allows you to determine which resistor you should use when you have a single LED or a number of the same color of LEDs in series. It displays resistor value, recommended resistor wattage as well as resistor color coding.
