There are two circuits, a and b, with equal wattage and therefore equal resistance. Both a and b have 3 lightbulbs (1,2,3 from circuit a and 4,5,6 from circuit b) and 4.5-volt batteries. The only difference between them is that circuit b has a short circuit at bulb 5. Answer a-g and explain the reasoning.
a. In which circuit is the current greater?
b. In which circuit are all 3 bulbs equally bright?
c. Which bulbs are the brightest?
d. Which bulbs are the dimmest?
e. Which bulbs have the largest voltage drop across them?
f. Which circuit dissipates more power?
g. Which circuit produces more light?
