How do the currents produced by a 1.5 Volt flashlight cell and a 12 Volt car battery compare?

Do you mean the maximum possible current, or the current in normal applications? Car batteries have low internal resistance since auto starter motors draw a lot of current, a CCA (cold cranking amperage) rating of around 600A is not unusual for a car battery some can be even higher.
A flashlight cell is not designed for that sort of current, while the maximum will depend on cell size and chemistry, I suspect a couple of amps might be a good guess at a maximum. However, the rechargeable NiCad or NiMH cells used in portable power tools can probably put out significantly more for short periods.
Driving the same load resistance the current from a 12V battery will be 8 times that from a 1.5V battery. Assuming the load is not overloading the battery (and it might overload the flashlight cell if the resistance is too small).
This is simple arithmetic: 12÷1.5=8

Compare the directions in which surface currents flow near the poles and near the equator?
Sixth grade work..... SMH
Why does the direction of polarization of light compare with the direction of vibration of the electrons that produced it?
the plane of polarization matches the vibrational direction of the electrons
How does the ground motion produced by a P-wave compare to the ground motion produced by a surface-wave?
The underground motion of a P-wave usually effects the us less than ones near or on the surface.
Where to find a lithium battery?
There are many places to find a great price on the best lithium battery. The first thing a person should do is check their manufacturer's warranty. One may be able to get one free. Next, it is important to compare rates online. This is a great way to see what stores around the world are selling such accessories for. Local stores may have great rates on a lithium battery too.
How does water gas compare to methane in terms of thermal energy produced?
The molar heat of combustion of methane (890 kJ/mol) is higher than that of water gas (525 kJ/mol)
How does the currents priduce by a 1.5 v flashlight cell an a 12 v car battery compare?
No real comparison. In simplistic terms the D cell 1.5 volt flashlight battery will produce around 15 ampere hours. A 12 volt automobile battery will produce from 300 cold cranking amps (CCA) to 800 CCA or more.
How do the current produced by 1.5 volt flashlight cell and a 12 Volt car battery compare?
They don't. Car batteries produce 100's of amps of current. a 1.5Volt flash light battery produces milli-amps at best.
How do the currents produced by a 1.5 volt flashlight cell and a 12 volt car battery compare if the resistance is the same?
12/1.5= 8. If I = Current from 1.5 Volt source and I2 = current from 12 V source then I = I2/8 or said in another way the current from 1.5V device is 1/8 of the current from 12 V device.
How does the amount of energy in batteries in a flashlight compare to the total amount of energy given off byt the flashlight as light and heat?
All of the energy in the battery, or most of it, is eventually given off as heat and light.

How does the amount of energy in the batteries in a flashlight compare to the total amount of energy given off by the flashlight as light and heat?
There is more energy in the battery than that given off as light and heat for two reasons. 1) Some energy is lost due to resistance in the battery. As current flows, energy is lost to heating of the battery due to this internal resistance. 2) As the battery operates, the voltage falls until it is too low to heat the bulb to incandescence. Yet energy remains in the battery, but this last energy is at too low a voltage to be useful.

Is a flashlight good model for suns light energy hit earth?
Flashlight is not good model to test sun light hit earth. The light of flashlight is too small energy to compare sun light.
How does the amount of energy in the batteries compare to the total amount of light given off by the flashlight?
Well more chemical energy in a battery means more energy can be converted to light energy. I believe that the light will last longen and\or be brighter.
