The resistor color code chart is always nice to have on hand ... The four most common for me are included on the front just below the Ohm’s Law equation. On the back is a cheat sheet for ...

[Jeff] over at Gadget Gangster has been having the same problem, so he built a talking resistor calculator to speak resistor values to him. The electronics part of the build is extremely simple ...

The calculator on your smartphone will handle this easily ... Let’s say we know that 2 amperes of current is going into a 100 ohm resistor. What is the voltage across the resistor? The formula is 2 ...

Using standard resistor values can greatly impact the accuracy and predictability ... The arguments are: 1) an arbitrary value in Ohms; 2) a desired tolerance value (1%, 2%, “E12,” “E96,” etc.); and 3 ...

(E.g., nine 1-ohm resistors for the first, nine 10-ohm resistors for the next, and so on.) 3) Set aside one resistor in each set. Bend the leads of the other eight resistors to fit across ...
