3. The diagram in Fig. 1 1.7 below shows three 10 2 resistors connected in parallel. What do you think the equivalent resistance of ten such resistors connected in parallel would be? Explain why. What about for 1000 resistors? You can either give a detailed explanation or a calculation. +9V 10 9 Figure 11.7: Diagram for Question 3 (b) What happens to the light bulbs when the switch is open? Which bulb is giving 01f more light? (c) What happens to the light bulbs when the switch is closed? Which bulb is giving off more light? ((1) Explain why the number of illuminated bulbs changes between the case with the switch open and the case with it closed
