What color is green positive or negative for DC?
green is ground regardless of ac or dc
What color usually represents positive in electricity?
If it is DC then red is positive and black is negative.
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
Can you plug 9V dc to 220v?
It is certainly unsafe.
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.
Will a 9V 300 mA charger work as a 9V 300 mA adapter for a Vtech Vsmile game as I bought a charger by mistake?
Sure thing. The voltage is correct, and it has enough capacity. Make sure that you get the negative and positive polarity right if you are putting your own connector on. Usually they have a graphic, showing that negative is in the center of the plug, and positive on the outer etc.
What the conclusion that can take in multiple dc power supply?
conclusion of dc power supply 9V
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.
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.
What is the meaning of the DC electrical terms Positive Neutral and Negative?
DC means "direct current." Normally this is provided by a battery or transformer. Positive - The positive contact where current flows into a circuit. Neutral - The ground wire in case something happens like a surge. Negative - The negative contact where current leaves.
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.
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.
