The rule with power adapters is generally that the voltage must be the same as the device's input voltage requirements. However, the amperage just has to be equal to or greater than the device's input current requirements. The device will draw as much current as it needs. But, mismatching voltages can destroy electronic equipment.
What else can I help you with?
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.
What size amplifier do I need to power 2 15 700w speakers RMS output power is 350w?
The speakers will work with any amp that outputs less power than 700 watts.
Will a 12v 2 amp device work with 12v 2.5 amp power cable?
Providing that you maintain the same voltage and above all, make sure that the polarities are the same, yes, it should work. It's OK to have a little more power available than the device requires but it shouldn't be less, which can cause the cable to over heat or cause undue stress on the device itself. It sounds as though you're using a wall adapter to run something, and the extra .5 amp capacity should be OK. But, when using a wall adapter, always try to keep as close to the rating of the device as possible. Wall adapters that provide more power than what's needed, can over heat because the extra power isn't being used. It's just being converted to heat. Since you're within 20 percent of the device's ratings, this shouldn't be a problem.
How does an op-amp differ from other amplifier suchas common emitter transistor amplifier?
A: They both use transistors. In actuality before an op amp becomes an op amp a discrete transistor made is made to provide it capabilities before it gets integrated into a substrate chip we call op amp. OP AMP have two input to work as a differential amplifier the input are bases closely match to provide virtual no voltage or current offset. Single ended amplifier has one input its reference is the signal source return.
Why op amp are called linear devices?
the output has the same shape of the input signal
Is it possible to plug a microphone into a guitar amp?
Yes, it is possible to plug a microphone into a guitar amp using a microphone input or an adapter.
Can you play cds in a guitar amp?
Some amps such as the Fender G-Dec have a CD input on them that allows you to play your CD player through the amp. On other amps, you need an adapter to go from the CD player output to the amp's input. It will work.
Can you use a 1200 amp adapter for 500 amp appliance?
Yes, the adaptor allows load currents of 1200 amps or less, and 500 amps is included in that. The voltage of a supply stays constant, the current that flows is determined by what power the appliance needs to run.
How does 12v dc 1.5 amp power adapter differ from 12v dc 3 amp power adapter?
The main difference is the amount of current each power adapter can supply. The 12V DC 3A power adapter can provide up to 3 amps of current, which means it can power devices that require more current compared to the 12V DC 1.5A adapter. This can affect the compatibility and performance of devices connected to the adapters.
Will an 12v 3a dc out put power adapter fry up a machine that is 12v 2a dc out put?
Youshould not parallel two DC output adaptors. If you meant to say that the second device needed an input of 12 V at 2 amps then the 12 V at 3 amp adapter will work as a power source.
What is the output waveforms of comparator using op amp?
why the out put is equal to the positive power supply of the op amp when the nonenverting aom input is greater then invertung input
Can a 12 volt 0.5 amp ac adapter substituted with a 7.5 volt 1 amp adapter?
No, it is not recommended to substitute a 12 volt 0.5 amp AC adapter with a 7.5 volt 1 amp adapter. The voltage and amperage ratings need to match the requirements of the device you are powering. Using a lower voltage adapter may not provide enough power, and using a higher voltage adapter can potentially damage the device.
How can you install a sub-woofer and an amp to a stock radio in a 2002 pathfinder?
if its a brand new amp use the high level input wiring if you purchased it used or if it does't have high level input you can buy an adapter for it at an audio shop best buy or even walmart
How can you change the 30v1000ma power output on your acdc power adapter to a output of around 30v1ma?
Your power adapter is rated up to 30 volts at 1000ma. (1 amp.) If you have a device which only draws 1 milliamp, then it should work with this adapter, as long as the voltage is correct.
What are the different ways to connect an external audio source to a guitar amp using the aux input?
You can connect an external audio source to a guitar amp using the aux input by using a standard 3.5mm audio cable, a 1/4 inch adapter, or a Bluetooth receiver.
Can you use a 3 amp adapter on 5 amp device?
NO
Can I use a 10 amp 125 volt power cord on my computer's 6 amp 125 volt input?
Yes, you can use a 10 amp 125 volt power cord on your computer with a 6 amp 125 volt input. The power cord's amp rating represents the maximum current it can handle, so it is suitable for your computer's lower amperage requirement. Just ensure the voltage matches to avoid any potential damage.
