The device that changes d.c. into a.c. is called an 'inverter'. Whether you can get one for 9 V is another question!
It is kind of transformers called center-tap transformer its main function is to transform primary voltage to 2 secondary voltages or vice versa. In your statement the transformer will convert the input voltage to 2 voltage each is 9v or the opposite it will convert the 2 input voltages with each 9v to a certain value depending on the turns ratio of the transformer.
Ohm's Law Voltage = Current x Resistance V = I x R I = 9/5000
A relay cannot be used to power a motor. It can be used to control the motor by wiring the motor circuit in series with the relay contacts.
A: No problem but don't expect the power to increase
A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.
You can this by using the transformer windings.You can create a high voltage pulse through the circuit.As this thing cannot be explained in this so you need to check the related link.

No. The adaptor will overheat.

Calculate the impedence of your 3V circuit in ohms. Figure the voltage you want to drop. In this case, you need to lose 9V. This is three times the voltage you are supplying, so the resistor should have three times the resistence of your 3V circuit. If your circuit has 100 ohms of resistence (impedence), then you would connect a 300 ohm resistor in series with your circuit.
It is a circuit that function in only two states, on and off...but it will never be stable
im not sure if this will work or not but... If you use a 9v battery threw an inverter, then a step-up transformer to convert 9v DC to 120v ac i think it will light the bulb, however current decreases when you do that and i dont know how much a light bulb needs..worth a try, i might actually try it now
yes, if the other adapter is a va
Yes, but the 9V can't deliver as much current as the AA can. Internally a standard 9V contains 6 AAAA batteries. It would be best to use all AAAA cells or all AA cells, depending on current requirement of the load.

To modify the input voltage to match the desired output voltage. Say you need 5V to operate TTL technology and you only have a 9V battery. You build an SCC change it from 9V to 5V.
You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
