You are given a 9 V battery and three bulbs rated atrespectively (9V, 5 W), (9V, 2W), and (12 V, 6W). Assume that the battery has negligible internal resistance and that the three bulbsobey Ohm's law and convert energy to light with equaleffeciency.
a) When the 5 W bulb is connected to the battery terminals,what current will be established in the bulb?
b) what is the resistance of the 6 W bulb?
c) The 6 W bulb is connected to the battery terminals. Howdoes its brightness compare ot the 5 W bulb (a)? Explain.
d) The 5 W and the 2 w bulb are connected ins eries with the battery. Which bulb will be brighter? Explain.
