[Henryk] just sent us his latest episode of simple LED circuit puzzles. In front of the camera he solders one pin of each of the 3 LEDs to a different switch. He then puts the three assemblies in ...

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 ...

In this circuit the following applies. When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. The currents in the branches of a ...
