In the below figures the current vs amper-hour rating plot of a 12V
battery is given. The figure on the right is the circuit where this battery is utilized as the power supply. Consider the following operation conditions
i. R1 = 110Ω for 5 hour
ii. R1 = 30Ω for 5 hour
iii. R1 = 20Ω for 5 hour
The internal resistance of the battery is Rint = 10 Ω.
Please, find the following
a) Amper-hour consumption for each operation.
b) Rate of each consumption to the capacity of battery (Hint: Capacity is specified for certain operation currents)
c) Total consumed capacity in percentages.
d) Remaining capacity in percentages.
e) Find the duration of operation with the remaining capacity (If any), if the
current drawn from the battery is 200mA.
