Extracted text: 1. Sketch the V-I characteristic curve for step 5. Is Ohm's law applicable for the bulb filament? Explain why. How can you conclude that from the graph? 2. For the circuit shown in Fig. (6), if the value of R1=1KQ, with tolerance=+5%, and R2= 2.2KQ, with tolerance =+10%, find the minimum current (I) that can flow in the circuit. R, 1KQ Vs 10V R2 2.2KO Fig. (6)
