How does the sum of the voltage drops across all of the resistors compare to the voltage supplied by the battery?

Question

a. The sum of all of the voltage drops will be equal to the voltage supplied by the battery.
b. The sum will be less than the voltage supplied by the battery because some voltage is left in the battery.
c. The sum will be more than the voltage supplied by the battery because the resistors add voltage to the circuit.

a.  Conservation of energy requires the sum of the voltage drops = voltage applied by source

oubaas · Answer

for an ideal battery :
The sum of all of the voltage drops will be equal to the voltage supplied by the battery.

for a real battery : 
The sum will be less than the voltage supplied by the battery because some voltage is left in the battery.
