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.
What else can I help you with?
Can you use 500 ma power adapter on a device that requires 625 ma?
No, the capacity of the device is too large. The adapter will heat up and may even burn its internal windings open.
Is a 100 milliamp RCD more sensitive than a 30 milliamp RCD?
No, the 30 mA one is the more sensitive because it is the only one that will operate at currents between 30 and 100 mA.
What happens if a 200 mA power supply is used on a circuit needing 2 amp?
If a 200 mA power supply is used on a circuit needing 2 amp it would overload the power supply. Two amps equates to 2000 milliamps. Trying to pull 2000 milliamps from a device that is only capable of supplying 200 milliamps is not advisable. The excessive current draw would most likely burn the wires open and render the power supply useless.
What value multiplier resistor is required to create a 0-100V range voltmeter from a 10mA meter movement if the meters coil resistance is 50ohms?
10 ma times 50 ohms is 0.5 volts. 0.5 volts is one two hundreth of 100 volts, so the multiplier resistor on 200 time 50, or 10,000 ohms.
What is the current in a 100 ohm resistor connected to a 0.40 volt source of potential difference?
V=RI or I = V/R so I = 0.4/100=0.004A or 4mA
Can a 6 volt mA adapter be substituted for a 6 volt mA adapter?
It sounds like the same thing to me.
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 a 9 volt 1600mA ac adapter be substituted for a 9 volt 300mA?
Yes, a 9 volt 1600 mA AC adapter can be substituted for a 9 volt 300 mA adapter. The mA number represents the highest allowable current to be drawn from the adaptor. The adaptor that you want to replace has only 300 mA maximum capacity. The new adaptor has five time the capacity of the old one which means that devices that draw up to 1600 mA can be connected to it. Depends on what you are pluging into.. if could possible run unit hot..
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 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.
Can a 5VDC 300 mA adapter be substituted for a 5VDC 500 mA?
Yes, it would actually be a little heftier power supply as to how much amperage it could draw without blowing out the internal fuse.
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 a 12 VDC 500 mA adapter replace a 12 VDC 1200 mA adapter?
It depend on what the load of the device that plugs into it is. The mA rating is the maximum amount of amperage that the adapter can produce. The 500 mA adapter will produce about a half amp whereas the 1200 mA adapter outputs 1.2 amps. So one is about three times larger that the other. Check the device that you are trying to power for a mA load and that will tell you whether you can use it on the 500 mA adapter.
Can a 12V 800MA adapter be used in place of a 12V 500 Ma adapter?
Yes
Can 9v 1000ma adapter work with a 9v 700ma device?
Yes, the rating of the adapter is the maximum amount of current allowed to be drawn from it. The adapter you state has a maximum of 1000 mA or 1 amp. If the device draws 700 mA's you will have 300 mA's of spare capacity.
Can a 6volt 600 milliamps adopter be substituted for a 6 volts 100 milliamps adopter?
Yes, you can substitute a 6V 600mA adapter for a 6V 100mA adapter. The important thing is to match the voltage (6V) while ensuring the new adapter can supply at least the same current (milliamps) as the original, to avoid damaging the device or causing underperformance. In this case, the 600mA adapter has a higher current capacity, which is safe to use with a device that previously used a 100mA adapter.
Can 12v 600 mA adapter replace 12v 1200mA adapter?
No, the replacement adapter has to be of an equal or greater value but never lower.
