How do you make a 12 volt motor work on DC?
You can make an easy experiment using a small DC motor: connect it on a DC power supply of nominal voltage of the motor (ex. the power supply is 12V and power up a 12V motor). Now squeeze the shaft and the speed is going down, let it free and the speed is going up again to the specific value of speed for 12V. How many watts is a 12 volt motor?
Can I use a 12V power supply on a 5V device?
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. 12v power supply connect 5v Device burning damge but which device Some device in side Electronic protection ckt so may be not effect
What is the difference between 12V and 12/5v?
It is Ohm’s law. Your device is R and 12/5V is V. Current is decided by Ohms law, I=V/R. With 12V your device will draw double the current and gets heated up because all current limiting values of your device are calculated for 5V source.
Is it safe to run a 12-volt battery on 5 volts?
At 5 volts, this was fine. I suspect at 12 volts, the current would do damage. What are the 3 dumbest things we spend too much money on? You’ve done what you can to cut back your spending.
What is the law of 12V?
Can a CD4049 inverter work at 12 volts?

Can I use 5V for 12V?
So now you know you can get 12V DC from 5V DC but as you increased the voltage, the output current must reduce to respect conservation principle. So in reality you can extract very limited amount of power from your converter.
Can you run a 12V motor on 6 V?
If you run the motor on 6v then its no-load speed will be about half what it would be at 12v, and its stall torque will be about half what it would be at 12v. [EDIT: I am assuming a permanent-magnet motor.]
Can I run a 12V motor on 9V?
It's possible to run a 12V motor on 9V, but it will run slower and with less Torque.
Can a 12V DC motor generate electricity?
A:yes every motor can produce electricity.
Can you run a DC motor at lower voltage?
What Happens When Running a DC Motor at Lower Than Nominal Voltage? The simple answer to this question is that a DC motor run below its nominal voltage will be capable of a slower no-load speed and a lower stall torque. Running a DC motor below nominal voltage generally will not cause any problems with the motor.
Can a 6V battery power a 12V motor?
If you give a 6 V to 12 V motor, the motor will run at half of its rated speed and the Torque will also reduce.
Which battery is best for DC motor?
7.2V: six AA or AAA rechargeable NiMh batteries is perfect for 7.2V DC gear motors. These are usually in a battery pack rather than as individual cells and you will need a more specific NiMh battery pack charger. 7.4V: two LiPo cells can often power a microcontroller and works great for 7.2V DC gear motors.
Can you power 12V with a 9V battery?
Most devices made to run on 9V have plenty of margins so they will work just as well on 12V, but better safe than sorry.
Can you power a 12V fan with 9V?
Yes, you can do it, but the battery won't last very long. It will probably run at about 3/4 the speed and draw about 3/4 the current (rough estimate) so around 100mA.
How much current does a 12v DC motor draw?
A low voltage (e.g., 12 Volt or less) DC motor may draw from 100 mA to several amperes at stall, depending on its design.
Can a small DC motor generate electricity?
It may surprise design engineers that both Brushed DC and Brushless DC (BLDC) motors can operate as generators. A brushed DC motor is appropriate for generator applications requiring a DC voltage output, while a brushless DC motor is suitable for AC voltage applications.
Does spinning a DC motor generate electricity?
A DC motor will generate a DC voltage if you spin it. That is to say, mostly a DC voltage.
How do you convert 12V to 9V?
To reduce a 12V circuit to 9V, place two resistors in series within the circuit. Find the difference between the two voltages (12V - 9V = 3V) to determine the total amount of resistance needed.
Can a 6V motor run on 9V?
You can run a 6V motor at 9V -- it will run faster but won't last as long.
What's the difference between 9V and 12V?
However, there is not much difference between 9V and 12V. It does not take much current to be drawn from the battery before it drops 2V at its terminals. A small mount of extra drop in the wiring and the internal 9V supply drops. After that, the available current from the controller drops quite quickly!
Can I use a 24V power supply on a 9V?
The negative effect will (probably) be damage to one of the circuits inside. 24V is nearly 3 times 9V so it is not a good idea.
Can I use a 12V 1.5A power adapter for something that is rated ... - reddit
Thanks for the quick response! I found the diagram - one on the router above the power port, and one on the power adapter label. They both show the same diagram, basically a minus sign with a circle around it on the left, then to the right of that is a 'C' with a solid circle inside, then to the right of that is a plus sign with a circle around it.
Can you use a 12V DC adapter for 5V DC device? - Answers
For a device requiring dc in 5v 500ma will a dc adapter with an output 12v 1000ma also work? No, you have to apply the correct voltage that the load requires.
How To Reduce Voltage From 12v to 5v? 5 Easy methods!
How do I reduce 10 volts down to 5 volts? You can either use a resistor or a diode to reduce the voltage from 10 volts down to 5 volts. It is highly recommended that you use a Zener diode as it doesn’t require additional components.
Can I use a 12v 3A power adapter on 12v 1.5A device? - Quora
Answer (1 of 13): Yes, you can use a 12V 3A power adapter on 12V 1.5A device. You can also use a 12V 0.5A power adapter but the charging time will be three times longer. If you are a cautious person then you should use a manufacturer recommended power adapter. But whether it is better than a gen...

Can a 12V battery burn out?
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.
Can a CD4049 inverter work at 12 volts?
Depends on the device. Some will operate just fine, some will produce smoke and many will just quietly stop working, never to work again. A lot of the digital parts I worked with at RCA were rated to 20 volts, and would have no problem with 12 unless the design caused too much current. A common shortcut we used was driving LEDs with the CD4049 hex inverter without using any series resistor. At 5 volts, this was fine. I suspect at 12 volts, the current would do damage.
Why does my motor fail to start?
Switch on the power supply and the motor will fail to start due to the physical resistance. The current reading should now be much higher. This is the Max Load current

Switch on the power supply and read the current on the Multimeter - This is the Zero Load motor current
What wire to connect multimeter to power supply?
Connect the Multimeter positive terminal (red wire) to the power supply positive wire which we previously marked with tape
Where should the transistor be placed after the motor?
Here's a link to why the transistor should be placed after the motor. Connect the motors second connection to the positive terminal of the power supply. Position the diode across the motor input and output breadboard rails ensuring the silver band on the diode is closest to the power supply positive rail. That's it.!
