Can I use a 5V for a 9V
In general the effect depends on the device and power supply. In general, connecting a 9V supply to 5V device could damage it immediately, or in long term, but it is impossible to say without seeing the schematics of the device how much excess voltage it can handle.
Can you plug a 9V pedal into a 12V power supply
In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it. There are some guitar pedals built to handle voltages higher than 9V. Those pedals will work perfectly fine with a 12V adapter.
Can I use a 10v adapter for a 9V guitar pedal
DO NOT USE ANY OTHER VOLTAGE AND AMPERAGE OTHER THAN WHAT THE PEDAL WANTS!!! YOU COULD DAMAGE IT SEVERLY. Just wanted to clarify that you have to match the voltage only. Most adapters can give out more amperage than what the pedal needs – that's okay, the pedal only takes what it needs and not more.
What voltage is pedal power
Voltage (9v, 12v, 18v, 24v)
Although 9-volt power is the most common, there are tons of pedals that require more. The important thing to remember is to only use the exact voltage specified by the pedal. Some pedals (overdrives in particular) are built to accept 9 volts or 18 volts.
Can 5V relay work on 9V
Alternately,if the current rating of the relay is low, you can use a linear voltage regulator to convert 9v to 5v and then connect the relay. Use a 7805 voltage regulator to step down 9V DC to 5V DC. Now with the 5V DC you can easily control the relay.
Can I use 5V instead of 12V
It will cause the device to draw more current than it is designed for and will likely burn out, causing fire hazards and explosions. In other words, if the applied voltage is more than the maximum rated voltage then the device will undoubtedly fail due to overvoltage.
Can I run 5V DC motor with 9V battery
Powering an 5V motor by a 9V battery can damage the motor. You can either add an voltage regulator or resistor to consume the excess voltage. These devices must support the current drawn, and produce heat depending on the voltage difference (4V) and current (145mA per motor), according to P=U*I.
Is it safe to use 12V charger for 9V
You shouldn't. Many electrical gadgets have extremely delicate constructions that cannot withstand even a very little voltage that is higher than what is recommended. Such as most of the time, a 9V guitar pedal cannot be powered by a 12V adaptor.
Can I use 5V adapter instead of 9V
Can I use a 5V adapter for 9V Simply No. Your device will probably be burnt. You will have to step down the voltage using a DC to DC converter or by using a specific resistor.
Can I use 5V for 10V
Yes, an opamp can easily amplify a 5V signal to 10V, but it requires an external power supply >10V in order to accomplish that. A boost converter is used to convert power at 5V to 10V when there is no other higher voltage supply available.
Can you power a 9V pedal with 18V
NO! YOU CAN'T DO THIS WITH MOST 9V PEDALS! Some pedals are designed to accept 9-18v, and it will say on the pedal or in the manual. But most 9v pedals are not designed to handle voltages higher than 9v.
What happens if you use the wrong power supply on a guitar pedal
I also learned that using a power supply of the wrong polarity can damage or destroy a pedal, but that some pedals have protection against using the wrong polarity.
Can I run 5V motor with 9V battery
Powering an 5V motor by a 9V battery can damage the motor. You can either add an voltage regulator or resistor to consume the excess voltage. These devices must support the current drawn, and produce heat depending on the voltage difference (4V) and current (145mA per motor), according to P=U*I.
Can a relay work at 5V
The 5V relay module can be used to control a load such as a lighting system, motor, or solenoid. It can also be used to switch AC or DC voltages. The maximum voltage and current that the 5V relay module can control is dependent on the specifications of the relay.
Is 5V stronger than 12V
So the 5V system is 2.4 times more efficient than the 12V system, meaning you need to provide 2.4 times as much power as a 5V system to achieve the same outcome. Where is all this extra power used up in the 12V system you may ask Well, it is dissipated in the form of heat!
Can a 5V motor run on 12V
You can not power a 5V motor with a 12V supply, unless you keep it submerged in liquid nitrogen to deal with the heat.
How to convert 5V DC to 9V DC
For 5V to 9V, the easiest way is to connect each signal to the base of an NPN transistor via a suitable resistor (say 10K) with the emitter connected to the common ground for both logic levels, and the collector connected to +9V via a suitable resistor (say 10K).
Can you power a 9V pedal with 18v
NO! YOU CAN'T DO THIS WITH MOST 9V PEDALS! Some pedals are designed to accept 9-18v, and it will say on the pedal or in the manual. But most 9v pedals are not designed to handle voltages higher than 9v.
Will a 12V LED run on 9V
The answer is “Yes”. A 12V strip can run on a power supply a little lower than its required electrical voltage, like a 9V alkaline battery. This setup is even entirely safe to operate.
What happens if I use a 5V adapter on a 12V device
That said, I'd suggest against using a 5 volt supply for a 12 volt device. For a start, if it really requires 2 volts (or close to it), you will have a problem because 12 x 2 = 24 watts, while 5 x 2 = 10 watts, so the power supply is under-specced to do the job at maximum load.
Is it OK to use lower voltage adapter
Choosing an adapter with a higher or lower voltage or current rating may cause the connected device to malfunction. This happens if the adapter's VDC is lower than the device's input voltage even when their current ratings are the same.
What happens if you put 12V on 5V
You cannot use a 12V power supply on a 5V. It will cause the device to draw more current than it is designed for and will likely burn out, causing fire hazards and explosions. In other words, if the applied voltage is more than the maximum rated voltage then the device will undoubtedly fail due to overvoltage.
Can you run a 9V motor on 12V battery
Using a higher voltage than the rated voltage can cause the motor to overheat and damage its internal components. The motor may rotate too fast: Using a higher voltage than the rated voltage can cause the motor to rotate too fast, which can lead to mechanical stress and damage the motor's bearings or other components.
Is it safe to use the wrong power supply
Choosing an adapter with a higher or lower voltage or current rating may cause the connected device to malfunction. This happens if the adapter's VDC is lower than the device's input voltage even when their current ratings are the same.
Can you use 5V for 12V relay
Also you can use relay with coil on 5V (relay is designed to work on 5V, there is 3V relay), or you can use both 12V and 5V in device, where 12V can be used just to run 12V relay.
