4. The circuit is returned to its original state. A fourth bulb (D) is connected in parallel with bulb B (not in parallel with B and C). (Sketch the bulb on the circuit.) http://www4.wittenberg.edu/academics/phys/pvoytas/p21806/labs/lab8_ohms/hw_3_997.pdf (copy and paste to view circuit) A. What happens to the brightness of each of the three bulbs B. What happens simultaneously to the current through point 3? C. What happens simultaneously to the potential difference between points 3 and 4? D. What happens simultaneously to the potential difference between points 4 and 2? 5. State Ohm’s law in words. For what type of circuit elements does it correctly
