Can you use a 8 volt 200 mA adapter to power a 6 volt 200 mA device?

It might work if the device that you are plugging it into has its own voltage regulator, there is no way of knowing this. Personally I would not take the chance. When a manufacturer designs a piece of equipment it uses a specific voltage for the circuitry to operate on. Varying from this voltage is not a good idea and most likely it will void the warranty if the device becomes inoperable.

Can a 9 volt 1000 m a adapter replace a 9 volt 200 m a adapter- the polarity is the same-this is not bein used as a charger its being used to power a guitar effect pedal in place of 9volt battery?
Some 9 V adapters rated for 1000 mA will provide 9 V at 1000 mA. If you use it on a 200mA device the voltage may go up to 10-15 V and if that device can not handle the higher voltage, it it could burn out. Better adapters will only put out 9 V exactly and have no problem. Be careful of revere polarity where the positive on one is the negative pin for the other adapter.
Can a 200 watt converter power 0.6 amp device?
Not unless the device is running at less than 333 volts.
Can you use a12vdc 2000ma power supply to power a 12vdc 1000ma device safely?
Depending on what type of power supply it is there are a few options.If the 2000mA rating means it'll supply up to 2000mA, you're already okay, although you should put a resistor in parallel with the device to safely dissipate extra power. You wouldn't want to exactly split the supply in case the device has current demand variations. It would probably be best to siphon off say, 750mA. Since it's 12 volts, from ohm's law: V = IR you'd want 12 = 750mA*R, or a 16 Ohm resistor. It would also have to handle the power output, where P = IV, so P = 12v*750mA = 9 W. This is a lot of power, but you could probably find such a resistor somewhere. (Try looking at sandstone power resistors)However, if the supply is powering a sealed device (eg something you wouldn't open up and tamper with), I think you'd be better off just finding the appropriate power supply.
Is there a difference between a 9-volt 200mA power cord and a 9-volt 2 amp power cord?
Yes, one outputs 200 mA of current and one outputs 10x that much current. There is also a very good chance that the circular plug will be a different size.
Can you make 220 volt AC current from 1.5 volt by step up transformer?
In principle you can but in practice it is not done. A 220 v supply might have to provide (let's say) 200 watts of power for a TV. That would mean that the current drawn at 1.5 volts would have to be at least 140 amps, and that kind of power is not normally available.
Can a 100 mA adapter be substituted with a 200 mA adapter?
A 9V 1A adapter will supply up to 9 Watts of power and a 9V 200mA adapter delivers up to 1.8W of power. The 200mA adaptor may not be able to supply enough power to a device that has been supplied with a 1A adapter. The 1A adaptor should operate equipment that originally used a 200mA adapter. Before using a different power supply, check that the outputs are both DC or both AC. If they are both DC, it is important to check that the polarity at the connector is the same for both. If AC and DC supplies are swapped or the polarity is swapped there is a risk that the equipment will be damaged.
Can a 9 volt 300 ma AC adaptor be used on a 9 volt 200 ma device such as the Tama Rhythm Watch RW105 programmable metronome?
Many times the plugs at the ends of the adapter will be different for different voltages and mA ratings. If it is the same, then look at your device (or the user manual.) It should give the input voltage and current ratings. If the amp draw of the device is greater than 300mA, do not use the ac adapter. It will damage the adapter and could damage your device. If the tuner came with a 800mA charger, then I'm sure you should go buy another for a few bucks at an electronics store.
Can you use a 1300mA universal adapter for a 200mA device?
Yes, the maximum that the adapter can deliver is 1300 mA or 1.3 amps. The maximum that the device will draw is 200 mA or .2 of an amp.

100 volts of ac are put across a 100 trun transformer primary what will be the voltage output if secondry has 200 truns what is power in each coil?
You have a 2-to-1 step-up transformer. The voltage across the secondary winding is 200 volts. The power in the secondary winding is the power required by whatever 200-volt device you connect across that winding. The power drawn by the primary winding from the 100-volt AC supply is somewhat more than the power delivered to the device by the secondary, since some power is lost in the transformer wire and core. That's why the transformer hums and gets warm.
What adapter has more power the 9v 600ma or the 9v 800ma?
The capacity of the 800 mA adapter is 200 mA larger than the 600 mA adapter.
Can you use a adapter 15VDC 1A to replace adpater 15VDC 200mA. will it fry my device?
No it will not harm the plug in device. The 1 amp relates to 1000 mA or in other words it has five time the capacity as the 200 mA adapter.
Can you use a 9V 300ma adapter to power a 6V 800ma device?
No, the mA rating of adapters is the maximum amount of load that can be drawn from the adapter. 1 amp is equal to 1000 mA. By replacing a 800 mA adapter instead of using a 1000 mA adapter is limiting the connected devices load by 200 mA. If the connected device draws 800 mA's or less then the adapter will work.
Can you use an AC adaptor - 6v dc 1300 ma to replace AC adaptor - 6 v DC 800 ma?
Yes you can. All the 1300 mA rating means is that adaptor can supply devices up to 1300 mA. The old adaptor's limit was 800 mA. The new adapter has 500 mA more in reserve if it is ever needed.
Can you use a 9v 600Ma adaptor to power a 9v 300Ma appliance?
I think you mean to ask if one can use a 9v 600mA adapter to power a 9v 300mA appliance. Yes, you can do that. A 9v 600mA adapter will deliver 9v at up to 600mA. A mA is one milli amp, or one thousandth of an amp. 300mA is 300 thousandth of an amp, 300/1000 or 0.3 amps. 600mA is 600 thousandth of an amp, 600/1000 or 0.6 amps, and is twice the current of 300mA.
Can a 200 watt converter power 0.6 amp device?
Not unless the device is running at less than 333 volts.
Can you branch a 9 volt 200 milliamp adapter to two-9 v 100 milliamp devices?
yes, but you must connect in parallel additive mode. if u connect in series then the voltage will be doubled to 18v.
