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.


A circuit that adds a positive or negative dc voltage to an input sine wave is called?

What is a positive DC voltage?

A positive DC voltage is an electric potential where excess electrons will flow from negative to positive.AnswerYou appear to be mixing up potential difference (i.e. voltage) with potential. There is no such thing as a 'positive' voltage if you mean 'positive' in the sense of charge! 'Voltage' means 'potential difference', and you cannot have a positive or negative potential difference in this sense. You can only apply positive and negative in this sense to potentials.However, if you mean 'positive' in the sense of direction, then a positive voltage is one that is acting in the opposite direction to a negative voltage within the same circuit. For example, where two batteries have been connected in opposition.


What is DC offset in signal generator?

A sine wave centered at zero will have a positive peak that is the same magnitude as the negative peak. This can be offset so the negative peak magnitude does not match the positive peak magnitude. For example a 1volt peak - neutral sine wave could be DC offset by 1 volt so the positive peak is at 2 volts and the negative peak is at 0.


On a light switch what color is normally the ground wire?

That depends on the country, and the type of circuit. In the US, on 120 volt circuits, the ground wire is usually a bare, uncolored wire or a green wire that is attached to a green terminal screw. DC circuits have a red positive, black negative, no designated ground. In other places, there are other voltages, other codes, and colors will vary.

What color usually represents positive in electricity?

If it is DC then red is positive and black is negative.


How do you tell a positive wire from negative wire with colors?

In a DC circuit Red is positive and Black is negative. In AC systems White is neutral and Ground is green or green-yellow stripe.


What is the colour Code of dc wiring?

Normally Red is the positive connection and Black or Green is negative.


If you have an air solenoid valve DC and the wires are Green Black and White. Which one is positive and negative?

Green= Ground Black = live White = Neutral


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.


Red and white cabel- which post do they connect to?

Red goes to positive post. (red is usually designated as positive hookup always with DC systems. White is considered neutral or negative post with DC systems. (color technically should be black instead of white.)

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.

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.


What direction does dc Voltage travel in?

It travels from negative to positive. The opposite of what you might think.
