Question Answer

Suppose we have a common anode RGB LED connected in a circuit with a resistor of 220 ohms. The LED has a forward voltage drop of 2.2 volts for the red LED, 3.5 volts for the green LED, and 3.3 volts for the blue LED. The forward currents for the red, green, and blue LEDs are 15 mA, 20 mA, and 10 mA respectively. Calculate the total voltage drop across the resistor and the total current flowing through the circuit.

Total voltage drop across the resistor is 9 volts and the total current flowing through the circuit is 45 mA. Related Questions What is…
