Still having a hard time solving for R1 R2 Vth and Rth Also

Thevenin Equivalent LEDs used are white and red. White LEDs are rated at 3.2v,2smA Red Leos are ratad at 2v, IsmA LOAD Each LED must have a resistor tu igkrt op. must pe limited thragh the LED So resistor must be used o Resistance may be calculated by: Calculations LEDs find he resistor needed forte LED opory ly illuminate armt limitng Gmula: Rs Ve ie LED, and is te current through LED oIF igv is applied to tu circuit: 15 MA resistor l resistor needed ISMA

Solution

In this question, method applied is correct for finding resistors

units need to be ocnverted to standard units

then we get Resiance for white as (18-3.2)/.025 = 592 ohms

and for red as 1066ohm or 1.6 approx kohm
