The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard - fire, explosion, etc. Mostly it will get damaged.
Can I use a 12V power supply on a 5V LED?
1 Answer. Putting two in series is not going to work, since you'd then have to interface the serial data line. You could however use a small DC-DC (such as the many LM2596 based) to convert 12V down to 5V. It would also reduce the current requirements in the wiring.Jul 31, 2019
What would happen if a voltage source of 12V is provided instead of 5V?
So, the 12V supply will simply drag the 5V line up to 12V, depending on what else is connected to the 5V supply - like ICs, which could be damaged. If each supply were an ideal voltage source then infinite current would flow and the universe would be destroyed.
Can you use higher voltage power adapter?
Higher current (A) is okay because the device won't use as much, but higher voltage (V) is going to “fry” it. Conversely, lower voltage is unlikely to cause damage since the device simply won't have enough power, but lower current can cause trouble because the power supply cannot provide enough.
Can I use an adapter with higher amps?
Can I use an AC adapter with higher amps? As long as the voltage matches that expected by the connected device, then yes, you can use an AC adapter capable of providing higher amps.
What does DC 4.5 V mean?
It stands for Direct Current. There is AC or Alternating Current which is what you have in the home. The receptacle is for a Wallwart or external power supply that converts 120 Volts AC to 4.5 Volt DC.Jul 11, 2004
Can I use a 5V 4a charger with a 5V 1A device?
Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
Can I use a 5V adapter to power a 12V device?
A 5V adaptor cannot drive a 12V device. Also, an adaptor of voltage higher than the device needed would damage your device.
Can 5V charge 12V battery?
No, u can't run a 12V motor on 5V supply because 5V supply can not provide much current to motor to rotate.
How do you reduce 9 volt voltage?
To reduce a 9V battery to 3.3 volts, use a zener diode, such as a 1N746 or a 1N4728A. Choose the appropriate one based on how much power it can dissipate. A 1N4728A has a 3.3-volt and a 1 W power rating. It can supply, on average, a stable 3.3 volts to a circuit or another component.Apr 24, 2017
How do you reduce the voltage of a battery?
Sometimes, your electronics project might just need a voltage source that's lower than the battery voltage you have available. When this happens, you can reduce your battery's voltage to any level you want by building a simple circuit called a voltage divider.Apr 24, 2017
