The wire described in (2) is removed. What happens to the brightness of eachof the three bulbs and to the current flowing through point 2 if a wire is con-nected from the battery terminal at point 2 to the socket terminal at point 5?4.The circuit is returned to its original state. A fourth bulb (D) is connected inparallel with bulb B (not in parallel with B and C).a.Sketch the bulb in the circuit.b.What happens to the brightness of each of the three bulbs?c.What happens to the current flowing through point 3?d.What happens to the potential difference between points 3 and 4?e.What happens to the potential difference between points 4 and 2?5.State Ohm's law in words. For what type of circuit elements does it correctlydescribe the behavior?6.Does a light bulb have a constant resistance? Explain. Is a light bulb ohmic?7.Does a resistor have a constant resistance? Explain. Is a resistor ohmic
