total voltage will be equal to voltage of each resistor because: total energy is conserved which means that energy provided by battery = energy used up in resistors that means that energy provided by battery PER UNIT CHARGE = energy used up in resistors PER UNIT CHARGE and energy per unit charge = voltage . does that help? I can't figure out exactly what is your question. Keep on asking until it feels natural. It is a good thing to ask question as long as you have even a slightest confusion.

Sep 25, 2014 at 8:30 | comment | added | Suchal | How do you propose to increase energy/time? charge/time=current. to increase current you will either need to decrease resistance or to use battery with higher e.m.f. | |
Sep 25, 2014 at 8:12 | comment | added | SMcCK | So if I increased the voltage ,the energy/time would increase leading to the charge/time to increase.And voltage drops will always balance such that it adds up to the total voltage provided by the battery. | |
Sep 25, 2014 at 7:46 | comment | added | Suchal | @SmCck you are forgetting that V does not mean energy but rather voltage which is energy/charge. Electrons at b do not know how many resistors are ahead but actually there will be less electrons/time as resistance increase which essentially means that due to less current, which is charge PER TIME, there will be smaller energy dissipated PER TIME. | |
Sep 25, 2014 at 7:32 | comment | added | SMcCK | Another question.What decides how the energy is lost?When the electrons are almost near b how do they just know there's another resistor ahead? If only the 2v resistor was in the circuit all the energy would be taken by the 2 v resistor and the extra will dissipate as heat. Why can't that happen here? | |

Made my point clearer.
