Can you use a 9v dc power adapter on a device that requires a 10v dc?

No. The 9 volt DC adapter has a built in bridge rectifier that changes the AC to DC. Usually it is a half wave rectifier but on some more of the expensive adapters a full wave bridge and capacitors will be used.

Will using a 12 v 1200 Ma plug for a 9 v 1000 Ma appliance work?
Attempting to run a 9v 1000mA device from a 12v 1200mA power supply will most likely damage it. Gree Fully, today's electronics are dependant on a precise set of values to operate efficiently. Ant deviation of any one value will effect the rest adversely. This will include values greater and less than recommended {i.e. 9.5V can not properly run recommended 9V nor 10V dependant circuits}. The components are manufactured with less and less tolerances I suppose for economical reasons. The days of seeing {+/-} are getting slim lol.
Can you safely use a universal AC adaptor set at 10V 300mA for a portable CD player that requires 4.5V 700mA?
Gary, If you do this you are going to toast your CD player. I suppose you are thinking because the VA that it will be ok. It won't. Your CD is not desinged to handle the higher voltage . This is really no different that taking a 120 volt microwave and trying to plug it into 240 volt source; and I know you wouldn't want to do that. The only difference here is amps for household stuff and milliamps for your electronics. Same result though; you get to go and get a new one. . Andy
What is the kinetic energy of a 10 kg bike that is moving at a velocity of 20.0 meters per second?
KE = 1/2mass velocity squared KE = 1/2mV^2 80 J = 1/2(10 kg)V^2 multiply through by 2 160 = 10V^2 divide by 10, both sides 16 = V^2 take square root each side and discard negative answer Velocity = 4 m/s
How many volts in an amp?
What you are asking is kinda like asking how many oranges in an apple Voltage is the measure of electrical potential Amps is the measure of electrical quantity a good illustration is a water pipe, you can have high pressure (volts) but unless the water is allowed to flow the quantity of water is zero. (amps)
Can you use a universal ac adapter set at 9v for a scanner that requires 10v?
It's not likely that you will be able to draw enough power for the 10v device, as you have probably found out by now.
What is the answer to -10v plus 6v?
It is: -10v+6v = -4v
What is the factor of 100v squared - 220v plus 121?
100v2 - 220v + 121 = (10v - 11)2

using a step-up transformer. ****warning***** will stress a power supply
Will a 220 outlet run your 230 welder?
Any device is designed most likely with some limitation of +-% A 10v is nothing to worry about however the current is something to worry about
What is the rms of 10v?
The rms of 10V is 6.02V. Take the peak voltage of the sine wave and multiply it by 0.707.
A model rocket was launched to an altitude of 54 925 feet how many feet above 10 miles did it travel?
h + vt -4.9t^2=54925 10+10v-4.9(10)^2=54925 500+10v=54925 10v=54925-500 10v=54425 v=5442.5

What purpose could there be for a 10V transformer buried in a closet attached to power?
Follow the secondary wires, and see where they lead. It could be a doorbell transformer. It could be an old telephone (Trimline? Princess?) power transformer - check yellow and black in that case.
