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 ...
What’s your favorite value of resistor? 1K? 10K? They’re all fine, but when you need nearly no resistance at all, nothing beats the good old zero-ohm resistor. Wait a minute! Resistors are ...
When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in ...
