Mathematics · Diode Circuit Calculations
In a series circuit connected to an 8 V DC source through a resistor R, two diodes (one Green LED and one Red LED) are connected in parallel with opposite polarities. Find the value of resistance R so that a current of 20 mA flows through the 'on' diode. Both diodes have an average turn-on voltage of 2 V.
