Can I use a 6V adapter for 12V?
If the device has its own internal switching regulator, the voltage probably won’t be a problem, but since the 12V power supply has a lower maximum power (12V * 0.35A = 4.2W, and 6V * 1A = 6W), it may draw too much power and the power supply will be damaged.
Can I use 5V adapter for 12V device?
A 5V adaptor cannot drive a 12V device. Also, an adaptor of voltage higher than the device needed would damage your device.
What is an ideal voltage source?
By definition, an ideal voltage source is a two-terminal element with the property that the voltage across the terminals is specified at every instant in time. This voltage does not depend on the current through the source. That is, any current in any direction could possibly flow through the source.
What will happen if I connect a 5V to a 12V?
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. In your opinion, what would be the average initial startup cost for product development?
What will happen if I use a 12V power supply?
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. Can a human carry 200 Kg on his shoulders, no, average human is designed to carry around 25 Kg only. The device will very likely burn out.
How do I connect an Arduino to a 12V power supply?
So in short, you connect the logic pins to your Arduino’s ground, Vcc and digital output pin(s), and connect the JD-VCC pin to you 12V power supply. Program your Arduino (or microcontroller of choice) to set the control pins low for activating the relay solenoids and high to deactivate them.
Do LED light bars run on 5V?
If they did run off 5V, then all you need to do is figure out how much current they draw, and insert an appropriate resistor. For example, if there are two light bars, each with two LEDs, then they’ll probably draw roughly 80mA total.
