Can I use a battery charger that is rated at 6V DC 1000 mA to replace one that was 6V DC 100mA or will this damage the battery?

No you should not do that. It will damage the battery and the battery will explode.

Can 1000mAh replace 1200mAh?
Provided other specifications meet the requirements, a 1000mAh power source will probably be able to replace a 1200mAh source - obviously, at reduced capacity (battery life). Other specification details must match however: both sources must have the same nominal voltage (e.g. 1.5V DC) and similar load characteristics (e.g. the ability to support 100mA with no less than 1.3V DC). Also note that it is generally possible to replace a non-chargeable battery with a chargeable one (subject to conditions detailed above), it is not generally possible to replace a chargeable battery with a non-chargeable one. Subject to the design of the device containing the battery, replacing a chargeable battery with a non-chargeable one can result in serious harm to equipment and personal.
What voltage can be deadly?
Electrical current is a fascinating and powerful tool. It can be both safe and deadly: the emissions from a Tesla coil, while awe inspiring, pass harmlessly around and through humans; yet, ramp up the current enough, and severe effects can occur.The major factors that affect a person are: the amount of current, measured in amperes or "amps"; the path the current takes through the body (i.e. through the heart); and the length of time the body is exposed as a circuit.The voltage, environmental moisture, whether the heart is in a beat or not, and the person's health can also affect the severity of the shock. The following list details effects of current. Note that 1000 milliamperes (mA) equates to 1 ampere (A).1 mA of current causes a bit of a tingling sensation, but can be dangerous under some conditions.5mA of current results in a slight painless shock. Strong involuntary reactions can cause injuries to the person.6-16mA results in a painful shock, and the individual is less likely to have control over their muscles.17-99mA results in extreme pain, respiratory arrest and strong muscular contractions. Death is quite probable at this point.100mA-2A results in uneven, uncoordinated pumping of the heart. Nerve damage begins here. Death is highly likely.At more than 2 amperes, the heart stops, internal organs begin to cook, and sever burns occur. Death is quite probable without immediate medical assistance.See the related links below for further details.
Can you use a 9v 300ma ac adapter in 9v 100ma socket its for a micro guitar amp?
yes but the device will not work property or nor work at all <<>> No, the 100 mA adapter will be too small to operate a device that requires 300 mA for its operation. By trying to draw a higher current than the adapter can supply, the adapter will heat up and possibly burn itself open. In other words the adapter will stop working.
Can you use a DC 9v 300MA adaptor to power a 9v 400MA device?
The voltage would match but the amount of power would likely not be enough to run the device. Under-power will not likely harm the device, but it won't work correctly. Always use the correct voltage/power for your devices!
Is it safe to use a 7.5 charger on a 7.2v battery also is it ok to use a charger with a 100mA higher charge rate than the battery?
Not that i can think of where you'd find a charger labeled for a 7.5 V battery, but - No. A charger rated for a higher voltages won't know when to turn off, and if it's also pushing a higher charge current it's likely to overheat the battery.
Can you use a 5v 1A charger for a 5v 500mA device?
No. In general, a charger needs to be able to figure out when the battery has reached full charge, otherwise the charger can damage the battery by overcharging it. You need to use the specific charger required for the battery. And, if you are trying to power a non-battery device that requires 1A from a 5V 100mA source, you will not be able to maintain 5V, so it will not work there either.
How long for first charge Ni-Cd 7.2V 700mah?
Depends on the charging rate, in Amps, of your charger. Very simply, if the charger current is rated at 450mA, then a 450mAh battery would require 1 hour to charge. Take the batter rating (450mAh) divided by the charger current rating (450mA), which equals 1 hour. If the charger rating is only 100mA, then it would take 4.5 hours to charge the same battery.
0.1A is equal to 100mA?
yes

Can i replace a dc 9 v transformer 200 mA for a 500 mA?
Yes. Yes, you can replace a transformer with one that has a higher current rating. The load on the transformer should be less than 200mA because presumably that is what the circuit was designed for. Since the current through the transformer should be less than 200mA, the 500mA transformer will not be damaged. The opposite is not true. You should not replace a 200mA rated transformer with a 100mA transformer, for example. If the current exceeds 100mA, the transformer could fry.
Can I turn a 9V battery output to 6V 100mA?
No! You need fewer cells for six volts. Most 9 volt batteries have six 1.5 volt cells, but a six volt battery has four 1.5 volt cells. In theory you could open the battery up and install a tap at the fourth cell, but that is pretty hard to do.
Can a DC 9v 100MA device use 9v 650MA adaptor?
sure, no problem! The power supplying device is rated as to its MAXIMUM current delivering capacity, so 100ma being less than 650ma, you could run up to 6 of those devices in parallel with that adapter. You should not try to run a 650ma device with a 100ma supply though.
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.
A series circuit has 100mA flowing through a 1.5kohm load What is the power dissipated by the load?
A series circuit has 100mA flowing through a 1.5kohm load. The power dissipated by the load is equivalent to 15 Watt. This is based on the formula, power is equals to square current times load.
What does 1800mAH mean?
This is a measure of battery capacity. It relates to how long a battery can produce a certain amount of current. For example, a fully charged 1500 mAh battery can provide 100mA for 15 hours (or 50 mA for 30 hours or 200 mA for 7.5 hours, etc.) The battery rating is the capacity for a new battery. After many charge/discharge cycles, you will start to see a reduced capacity.Related note: The capacity of a battery doesn't relate to the maximum current you can draw from the battery - that depends on several factors including the type of battery, its size and construction. For example you might be able to safely draw 15 Amps from a hobby style 1500 mAh Lipo (Lithium Polymer), but don't try to get 15 Amps out of 1500 mAh AA Nicads.
With a nine volt battery and different measured resistors in a series circuit with an LED how much current will flow through the LED?
Basically the current should be limited to 20ma Actually the heat dissipation of the device cannot be exceeded. Some LED can be run at 100ma or more depends on the device power dissipation envelope.
