- Table (4.1) Rs = 100 Q Reading RL (Q) IL(mA) VL(V) PL(mW) 1 20 54 1 40 48 1.7 3 60 42 2.3 4 80 38 2.6 5 100 34 3 6 200 22 4.1 7 400 15 4.8 8. 600 12 5.2 9 800 10 5.4 O 2. Using Table 4.1 plot a graph between values of PL versus RL. Find the value of the load resistor for which the power dissipated is Maximum. How is this value related to the series resistance Rs. (Note: Plot PL as dependent variable ). 3. For what value of the load resistance RL was: a) The load current a maximum? b) The load voltage is maximum? 4. Using the expression for PL power dissipated in the load resistance as a function of the load resistance RL, determine the condition for maximum power. (differentiate PL with respect to Ri and set dPL/dRL=0) 5. Compare the value of Ru at maximum power found in (2) with that found in (4) above. 6. If the internal resistance , Rs, is larger than the load resistance RL, which resistance will dissipate more power? 55.
