Two light bulbs have constant resistances of 400Ω400Ω and 800Ω800Ω. If the two light bulbs are connected in series across a 120-V line, find
a) the current through each bulb;
b) the power dissipated in each bulb;
c) the total power dissipated in both bulbs. The two light bulbs are now connected in parallel across the 120-V line. Find
d) the current through each bulb;
e) the power dissipated in each bulb;
f) the total power dissipated in both bulbs.
g) In each situation, which of the two bulbs glows the brightest?
h) In which situation is there a greater total light output from both bulbs combined?
