How can you reduce the current from a 12v 1100 mA battery to power a 12v 100mA computer type fan or is it necessary to do so I dont want to burn out the fan?

The 12 volt fan will draw 100 mA from a 12 volt battery. You don't need to do anything to reduce the current. Your battery rating is probably really 1100 mAh; 1100 milliAmp-hours. You should get 11 hours of operation from your 1100 mAh battery if your fan is only drawing 100 mA.

What is DC battery?
All battery is DC battery. DC is meaning Direct Current. Battery voltage is steady, not change, except reduce when battery go flat.
Should you leave a laptop computer unpluggrd except to recharge?
No. Leave it plugged in. Each discharge and recharge of the battery is a cycle and will reduce the efficacy of the battery. The battery will still age and reduce but a good computer will keep it trickle charged when it is at full capacity preserving or extending its life a bit vs full discharge and recharge every day.
How long should you charge a car battery?
Most charges simply reduce power when the battery is fully loaded. If you're in a hurry, look for when the charge current drops.

I'm using a 18.5 volts 3.5 amps charger to charge a 12 volts battery I want to reduce voltage to 15 volts and current to about or a little less than 2 amps How to reduce charging current and voltage?
You need a regulator.
What is the average expected battery life for a Dell Inspiron 6400 battery?
The battery life on a Dell Inspiron 6400, 9 cell battery can last anything from 3h30mins to 5h30mins. The mainly depends on how the power saving mode has been set, when you reduce the computer's performance you save battery life.
Three identical bulbs are connected in parallel with a battery of 6A If one of the bulb gets fused what will be the total current drawn from the battery?
As the lamps are identical, and all three draw a current of 6 A, then each lamp must be drawing 2 A. So, with one of the lamps disconnected, the current drawn from the supply will reduce to 4 A.
What can be used to reduce to current in a circuit?
A: Any resistance added in series will reduce the current unfortunately will also reduce the voltage

What can you do to a closed circuit consisting of a battery a light bulb and a switch that would decrease the amount of current?
To increase the current you either need to reduce the resistance of the load or increase the voltage. Typically a higher wattage light bulb will decrease resistance or you could put multiple batteries in series.
Does computer reduce cost?
You blew a thousand dollars on a computer. Of course you reduce no costs.
Can battery test good when bad?
With no load attached, a battery can measure full voltage (potential). However, as soon as a load is put on it (current s drawn), the internal resistance in a defective battery will also draw current thus reduce output. If this is a car battery, have your local service station or garage do a cranking power test; thisi will prove if the battery is good or not. Be sure to take you old defective battery to your local recyling depot as it contains lead (poisonous metal) adn corrosive Sulfuric acid). Cheers Malcolm
