Using different voltages of power in the power supply is possible as long as the new power supply and the amount of current you want to use can run the system you want to run. For our case, using the 9v in place of 5v is possible, but it will supply more current that might cause the device to overheat.
Depending on your needs and reasons as to why you want to change the power supply, you should use the power supply that will run your machines and have the recommended amount of current. Having enough power is good since you will run and use your machines effectively.
The article below will discuss how one will use a 9v power supply in place of a 5v. It will also discuss the measures one should take before changing the power supply.
Using a 9v power supply on a 5v
Changing the power from 5v to 9v will affect the running and functionality of your devices. It is 9v power supply on your device might work for some time but will eventually lead to the voltage drop on the internal regulator of the device. It will cause the circuit to overheat and burn out after some time.
Before changing the power supply, make sure that the power supply is regulated, which means that the output power should be very close to 12v regardless of the load. Since all the electric devices have the input and the output voltage and current values, you should check them before changing the input power. You must know the effect of changing the input power on the device and how it will affect the output power.
For our case here, we want to change the power supply from 5v to 9v; it will now depend on the device we are using. In general, when we try to connect a device rated 5v to an a9v power supply, it will immediately or later damage the system because more power is now supplied into the device than the rated power. But sometimes, such scenarios are impossible when we do not detail how much excess voltage the device will handle.
Using the 9v power supply in place of a 5v is not a good idea if you want your systems in the circuit to be in a good state. You must ensure that you have an adapter or regulator to ensure that the circuit device receives or gets the recommended power given by the manufacturer. Exceeding the power supply will burn out your devices whatsoever, and therefore you should ensure that you use the required power in your circuit.
Can I use a 5v on a 9v?
Using the 5v power supply on a 9v power supply or device will work for some time. The 5v will work, but since there is a voltage drop in the circuit or the internal regulator will make the entire circuit or the device blow and burn out if you will not change the power as expected or as usual. Therefore, you shouldn’t supply power that exceeds the required and needed power or power that is not enough to run your systems or any given device that you want to power it on.
The voltage dropout in the system or the adapter is due to the resistance that the adapter you are using, making the circuit overheat or burn out if the same current will continue to flow. It is safe in any circuit that you pass or have the correct power supply to avoid such voltage dropouts or power surges that might damage or affect your devices in the circuit. But some guidelines will assist one to change the power supply from 5v to 9v without having any problems in the circuit when you are supplying the power supply.
Steps to jump from 9v to 5v power supply
Most devices and circuits have ICs’ that require the 5v DC power supply to run and function as expected. Therefore when one wants to work with a power supply of 9v, there will be a problem in getting the 5v dc power supply for such circuits. There are simple steps that will help one get 5v voltage of power from a 9v power supply source. Below are some methods and steps to help you jump from a 9v power supply to a 5fv power supply. The following steps and methods can change power from 9v to 5v power supply.

1. Design a simple circuit
i. Ensure that you have all the necessary tools to complete the process, such as the 5v power supply, wires, resistors, capacitors, LM7805, pins, Multimeter breadboard, indicators, copper clad board, and power regulator chips. Create a simple complete circuit that will be used in the process.
ii. Modify the breadboard according to the design of your circuit.
iii. The following simple step is to design some pair of pair pin headers that will be used as the inputs and the other two pairs used as the outputs. The main reason for having the pins is to help improve and boost the mechanical connection to the board.
iv. Ensure that the two output pins should be oriented downwards so that the connection will be accessible when you want to connect the input and the output connections.
2. Populate the circuit and cut in the entire circuit
i. It will depend on the cutting/etching style you want to use; cut and etch the circuit and begin testing it. It would be best to use the thick traces of wires when you are etching the circuit since it will give the best and most reliable results. Thin traces are also in the circuit but depend on your preferences.
ii. While populating your board, start the pin headers. From there, the headers of the input pins are typically inserted and are soldered at the top and left sides of the breadboard.
iii. From there, the connection pin headers are pushed through the board, and this is to ensure that the plastic pin headers housing will not have any protruding pin. The pins must be at the copper side of the board since you plug the circuit into the breadboard[Ma1] .
iv. Solder the resistors after the capacitors follow the pin headers. Here you must note the capacitor’s orientation since they are the polarized electrolytic capacitors with opposing sides that face one another on the board.
v. Ensure that the LM7805 regulator is soldered into the holes on the board and also increase the size of the holes in the board so that the regulator will be able to fit into the holes since its legs are more comprehensive than the holes in the board. The heat sink will overheat during the process because more voltage will be dissipated.
3. Connect the circuit to the power supply
i. After the connection is over, complete the connection by connecting the power supply.
ii. Now plug the entire module of the process into the breadboard and connect it to the power supply.
iii. When the circuit is correctly connected and the circuit is powered, the LED in the circuit will light up.
iv. When you try to test the power in the circuit using the Multimeter, you will get the result reading approximately 5v that is 4.9v. The process will be complete if you can read some results in your Multimeter.
Some techniques could be used to convert the power supply from 9v to 5v when you want to change the ratings of your power supply. One of the most common techniques is using the voltage divider and the Zener diode. These are ways that one will use to convert the power supply from 9v to 5v without having a problem with the power supply.
Changing the power supply ratings is possible as long you know how you could convert the size of the power supply. It is not good to use excess or less power in any device or circuit. It is because excess or less power will affect the functionality of the devices.
In converting or changing the power supply, you should ensure that you use the correct techniques and methods of converting the power supply, such as using the Zener diode or voltage divider. It will help you not have problems when you complete the circuits or turn on your device.
