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.
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.
The speakers will work with any amp that outputs less power than 700 watts.
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.
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.
the output has the same shape of the input signal
12v 1.5amp power adapter is 18 Watt, can't load more than 18W power consumption,3amp power adapter can load 36W.
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.
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.
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
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.
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
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.
Sure
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.
NO
if u mean rareiable gain amp , its a device to control sound input power
I should expect a real-world op-amp to have 5connections:-- the inverting signal input-- the non-inverting signal input-- the signal output-- the power supply input-- the ground connection.
