"Since, you have asked for handwritten solution, according to our guidelines, we cannot provide handwritten solutions." “Since you have posted a question with multiple sub-parts, we will solve the first three sub-parts for you. To get the remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.”. Here, we have given circuit #1, where a LED is present in series with the resistor and a supply voltage of 12V is given to the circuit. The V-I relationship curve is also shown. We have to observe the value of the VD . The VD is the forward voltage of the LED. So, we will follow the curve when the current through the LEDs is 10mA\ for Red LED first. And, similarly for Green and the Blue LED. So, we will get the forward voltages for the LEDs at the required value of current. Then, we have to justify if the LED is turning ON or not. Then, we have to calculate the resistance of the Red LED. To calculate the resistance of Red LED, we will take the value of effective voltage. So, we will calculate the effective voltage and then apply the formula to get the resistance of Red LED. The forward voltages for the LEDs, when the current of 10 mA or 0.01 A is flowing the circuit #1. VDRed=1.75 VVDGreen=2.2 VVDBlue=2.5 VThe LED is connected to the supply of 12V voltage. Because, the positive end of the LED is at a greater potential than that of the negative end, and the forward potential difference of the LED will be less than the voltage supply, so the LED will be lighting up.Given : Supplied Voltage=12 VCurrent=10 mA We have observed the value of forward voltage drop in Red LED form given graph as 1.75 V. so, we will calculate the resistance of Red LED as: R(Red LED)=VeffI So, we can calculate the effective voltage across Red LED as : VeffRed=Supplied voltage-forward voltage drop in Red LED so, R(Red LED)=12 V-1.75 V10 mAR(Red LED)=10.2510×10-3R(Red LED)=1.025 kΩ
