Yes...(if I'm understanding your question correctly). You want to use the 600mA adaptor on a device that once used the 100mA adaptor? Yes....you can go higher with mA, but not lower.
Use a rheostat to lower the voltage to six volts
Watts = amps x volts, Amps = Watts/Volts, 65/240 = .27 amps or 270 milliamps
Amps and volts are two different values so in your question they can not be compared. If you want to know which one can do the most damage to a human body then the amperage wins hands down. The following list is the tolerances that the body can stand. 1 amp equals 1000 milliamps Less than 1/2 milliamp no sensation 1/2 to 2 milliamps Threshold of perception 2 to 10 milliamps muscular contraction 5 to 25 milliamps painful shock (may not be able to let go) Over 25 milliamps Could be violent muscular contraction 50 to 100 milliamps Ventricular fibrillation over 100 paralysis of breathing.
These do not convert. ma (milliamps) is a unit of electric current, while volts is a unit of voltage. They are related by Ohm's Law: V = I*R, with V is voltage (volts), I is current (amps), and R is resistance (Ohms).
The dangerous amount of current is not in the amp range but in the milliamp range as per the following. One amp is equal to 1000 milliampsMilliamps are dangerousLess than 1/2 milliamp no sensation1/2 to 2 milliamps Threshold of perception2 to 10 milliamps muscular contraction5 to 25 milliamps painful shock (may not be able to let go)Over 25 milliamps Could be violent muscular contraction50 to 100 milliamps Ventricular fibrillationover 100 paralysis of breathing.

YES!If you have a TV antenna amplifier rated at 12 Volts and 200 milliamps, you can use any power supply that will deliver at least 200 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. note: 200 milliamps is 0.2 amps. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 200ma that it needs.
Yes connect all 3 batteries in series. 6+6+12=24 volts.
12V 5A = 12V 5000mA
No. Volts is the "pressure" of the electricity. If a single 3.6v led required 20 milliamps (amps is the "amount" of electricity) you would need to supply two of them with 40 milliamps but at 3.6 volts.
Yes. If you have a device rated at 12 Volts and 150 milliamps, you can use any power supply that will deliver at least 150 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 150ma that it needs.

2 volts across 100 kOhms produces 0.02 milliamps (or 20 microamps) of current. Ohm's law: Voltage = Amperes * Ohms, so Amperes = Voltage / Ohms.
12v 1000mA means that the maximum output of that unit is 1000 milliamps at 12 volts. 12v 150 mA means that the maximum output of that unit is 150 milliamps at 12 volts. So if you need 150 milliamps at 12v either will do. BUT if you need over 150 milliamps at 12v then you must go for the 1000 mA unit. By the way there are 1000 milliamps in 1 amp.
