A 9V DC (direct current) supply can be either positive or negative, depending on how it is configured. Typically, in most applications, a 9V DC source is positive, meaning the positive terminal has a higher voltage relative to the negative terminal. However, if the terminals are reversed, it can be considered a negative 9V DC. The designation of positive or negative is determined by the polarity of the voltage applied.
What else can I help you with?
What color is green positive or negative for DC?
green is ground regardless of ac or dc
Can a 9v dc motor produce 9v when it is used as an alternator?
A: No problem but don't expect the power to increase
What color usually represents positive in electricity?
If it is DC then red is positive and black is negative.
What will happen to DC signal if positive probe connected to negative terminal and negative probe connected to positive of DC supply oscilloscope?
If the positive probe of the oscilloscope is connected to the negative terminal and the negative probe is connected to the positive terminal of a DC supply, the oscilloscope will display an inverted signal. This means that the voltage reading will be negative, effectively showing the opposite polarity of the actual DC voltage. The magnitude of the reading will remain the same, but the trace on the oscilloscope will appear flipped around the zero voltage line.
What the conclusion that can take in multiple dc power supply?
conclusion of dc power supply 9V
You are wiring a LED lamp through a transformer you have a polarized plug and you know positive and negative The transformer is marked live and neutral Does live correspond with positive or negative?
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
Why all telecom dc powered equipment is designed with negative inputs like -48 -60?
AC currents alternate from AC to DC in a constant wave. The DC current is a direct and consistent current demonstrated to the negative reading. AC traveling from negative to positive and DC traveling in negative.
When welding with 7018 rod is the electrode holder positive and the ground negative?
Yes, the electrode holder (stinger) is positive and the ground is negative which means you would be welding DC positive.
Is negative DC dangerous?
There's no such phenomena as negative DC. Minus sign only means, that current is flowing the other way than you are measuring. It's danger is exactly the same as "positive" DC.
Can i use 9v dc with 12v dc?
No. 9 v is only 75% of 12 v.
How can you determine the positive and negative terminals on a car speakers?
you can take a 9v batt and tap it to your speaker wire. Hold one wire to a terminal on the 9v and tap the other on and off the opposite terminal if the speaker pulls in wrong polarity if the speaker pushes out its correct. Then just make note of which one was on which terminal of 9v and your good to go
What will happen to dc signal if positive probe connected to negative terminal and negative probe connected to positive of the dc supply?
If you are referring to using a volt meter then you will just get a negative reading on most modern digital meters. If you are using an old analogue meter you may get no reading.
