Question

http://i50.tinypic.com/msm44h.gif Consider the figure above. Bulbs A, B, C and D are identical. a) Suppose bulb B has been removed from its socket (leaving an open circuit), but with bulbs A,C and D still in place. What happens to the brightness of bulbs A and D when bulb B is put back in? A and D brighten A and D remain the same A dims, D brightens A and D both dim A brightens, D dims b) Suppose bulb D is removed from its socket (again, leaving an open circuit), but bulbs A,B, and C are left in place. What happens to bulbs A and B when D is put back in? A brightens, B dims A dims, B brightens A and B remain the same A and B both dim A and B both brighten You have two resistors which may or may not be identical. Which way of arranging the two resistors would result in the lowest equivalent resistance? In series Neither series nor parallel In parallel In series and in parallel you observed that the voltage across a real battery changes when current flows through it. What happens to the voltage across the battery when the load of the battery changes. More than one answer may be correct. Choose all correct answers. The voltage across the battery increases slightly when the current decreases. The voltage across the battery decreases slightly when the current increases. The voltage across the battery increases slightly when the current increases. The voltage across the battery decreases slightly when the current decreases. next question: http://i46.tinypic.com/zyekh.gif A light bulb is connected to three identical and ideal (no internal resistance) batteries in three different ways as shown below. In which circuit the light bulb is brightest? all the same c b a
