Another law applied to components connected in series is that the voltage drop across each component will add up to the source voltage value. north face men\u0027s hydrenalite down hoodie

"WebMiniature indicator LEDs are normally driven from low voltage DC via a current-limiting resistor. Currents of 2 mA, 10 mA and 20 mA are common. Sub-mA indicators may be made by driving ultrabright LEDs at very low current. Efficiency tends to reduce at low currents, [4] but indicators running on 100 μA are still practical.
