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.
What else can I help you with?
Will 9v 300mA power adapter work with a 9v 700mA device?
No, the adapter's power output has to be equal to or greater that the current draw of the device.
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!
Introduction of clap switch?
This circuit can switch on and off light a fan or a radio etc;by the sound of a clap This circuit is constructed using basic electronic component like resistor transistor relay transformer capacitor .This circuit turns on light for the first clap . the light turns on till the next clap .for the next clap turns off this circuit works with 12v voltage . therefore a step-cown transformer 12v/300ma is employed. The working of the circuit is based on amplifying nature of the transistor . switching the nature of transistor and relay as an electronic switch.
What size resistor is needed to allow a 220 volt coil in a relay operate on 277 volts?
You will need to know the amount of current flowing through the coil when 220 volts is applied across it. A resistor in series with the coil will limit the current so that the coil only sees 220 volts. The resistor will need to drop 57 volts. So, 57 volts divided by the current in amps will give you your required resistance. You will need a resistor with a high power dissipation rating with 57 volts across it. Your resistor will probaly need to dissipate several watts. For example: A 220 volt coil with 300 milliamps (.3 amps) will require a resistor of 733 ohms. The power dissipation of the resistor would need to be 17.1 Watts! You might try using a light bulb as a series resistor. Ensure that it can handle 57 volts. To complicate matters, is that AC or DC you are using? AC relays have inductance build in, in order to increase the specific "ac resistance", thus the same coil could use as little as 0,001A so you will need a very low value resistor. Anyway, if any 220V relay uses as much as 300mA, I doubt if you will be able to pick it up with one hand! Such a relay coil will draw about 66W of power! I have a 16A rated contact 230V relay. Its current is 0,0015A that is equivelant to 0.33W at 220V!
Can a 9 volt 100mA ac adapter be substituted for a 9 volt DC 300mA adapter?
No. an AC adapter will not work for equipment that needs DC.
Can you use a 9v 300mA adapter on a 9v 200mA device?
No. The adaptor will overheat.
Will 9v 300mA power adapter work with a 9v 700mA device?
No, the adapter's power output has to be equal to or greater that the current draw of the device.
Can you use a 300mA adaptor on a 1A device?
Yes, you can use a 300mA adapter on a 1A device, but it may not work properly or could damage the adapter. The device may draw more current than the adapter can provide, leading to insufficient power, potential overheating, or failure of the adapter. It's always best to use an adapter that meets or exceeds the device's current requirements for optimal performance and safety.
Can you safely use a universal AC adaptor set for 9V 300mA for a game that requires a 9V 700mA?
No, a power adapter must supply the same voltage, same polarity, and at least as much current as the load requires. Your adapter can only supply 300mA, which is less than the 700mA required by the load.Your game probably will not turn on and the power adapter may be damaged.
Where do you get ac to ac adapter with output 6v 300ma for your cordless phone for india?
Contact the manufacturer of the 'phone or visit a telephone retailer.
What is the difference between a 9v 300mA Adapter and a 12v 300mA Adapter?
difference is 2.7 amperes in numbers will be 12 volts 3 amps and the other will be 12 volts .3 amps
Will a universal ac adapter that says it is 1.5-12v up to 300ma be used to charge a portable DVD player that uses a 9 v1.5 a battery?
no
How many A does 300mA equal?
300mA (or milliamperes) is equal to 0.3A (or amperes).
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 you power a 9v 700ma device with a 9v 300ma adaptor?
No. The device will try to draw 700 milliamps which will overload the 300 milliamp adapter most likely causing it to burn out and possibly catch fire.
Can you use 5cV DC 800mA adapter in place of 6 V DC 300 mA adapter?
No, you should not use a 5V DC 800mA adapter in place of a 6V DC 300mA adapter. The output voltage and current ratings of the adapter need to match those required by the device you are powering. Using an adapter with lower voltage or significantly higher current may damage the device. It's best to use an adapter that matches the specified requirements.
