Figure 6 shows a circuit diagram of an adjustable voltage regulator that uses the LM317. Assume that VREF = 1.25 V and ladj = 100 μLA. [3] 5.1 Calculate exact values for R₁ and R₂ to obtain an output voltage of 10 V. [4] 5.2 Modify the circuit to vary the output voltage between 10 V to 12 V, by adding a variable resistor R3. Draw the full modified circuit diagram and calculate the value of the variable resistor R3. Use the values of R₁ and R₂ calculated in the previous question.
