But the phototransistor is mostly preferred over … Nettet7. jul. 2024 · But there are some limitations in connecting in series as well. You can not operate 4 LEDs of 3 volts with 6V of supply because 4 LEDs of 3V are equal to 12V so they require 12V DC. In parallel, you can do that by simply connecting each LED with a separate resistor. The diagrams below show you how LEDs are connected in Series …
