A 12V car battery dies not so much because its voltage drops but because chemical reactions increase its internal resistance. A good battery connected with jumper cables can both start the engine and recharge the dead battery. Consider the automotive circuit.
a. How much current could the good battery alone drive through the starter motor?
b. How much current is the dead battery alone able to drive through the starter motor?
c. With the jumper cables attached, how much current passes through the starter motor?
d. With the jumper cables attached, how much current passes through the dead battery?
e. With the jumper cables attached, in which direction current passes through the dead battery?

6) Car batteries supply a "nominal 12V voltage, but due to the internal resistance of the battery the actual voltage can be somewhat smaller. Consider this situation: Cars have an electric starter motor that draws 90A of current to turn over the engine pistons and start the car. While this 90A current is being drawn from the battery, the terminal voltage across the battery drops down to 11V. Use this information to find the internal resistance of the battery.

Consider the circuit below. It is something you might use to
approximate the circuit being used while trying to jump start a
car.
a) The elements in this drawing represent the dying battery
and its internal resistance, the jumper battery and its internal
resistance, and the starter motor. (Remember the jumper battery is
used to charge the dead battery and power the starter motor.)
Identify which parts represent each and explain your
reasoning.
b) Find the current in the motor...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
