Parsing various resistor band colors is fairly simple once you know what each color ... for controlling the current in an electrical circuit. This is particularly important if your project uses ...

Using properties of a series circuit, the sum of the voltages across the LED and resistor R must equal the supply voltage. \({V_s} = {V_{LED}} + {V_R}\) Now substitute the supply voltage (\(6V ...

Our Circuit Design Calculators for Engineers and Students are free-to-use tools that help you quickly determine key parameters ...
