What color is green positive or negative for DC?
green is ground regardless of ac or dc
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
What is the difference of DC and pulsating DC?
DC: constant current in the forward directionPulsating DC: An AC signal which has it's negative components blockedA: The terminology applies to a VALUE of DC being interrupted by its absence periodically or random
Which is more dangerous AC or DC?
I am not 100% sure but I think DC is more dangerous than AC.Both are dangerous. It is difficult to put numbers on it, as there are too many variables which determine the amount of current which flows through you when you get a shock. There is only one safe course when dealing with electricity, and that is to assume it is always dangerous and always avoid touching anything live.
What is frequency of dc?
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
Is 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.
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.
Do steroids work?
Yes they do work, and yes they are dangerous and have many negative side effects.Yes they do work, and yes they are dangerous and have many negative side effects.Yes they do work, and yes they are dangerous and have many negative side effects.Yes they do work, and yes they are dangerous and have many negative side effects.Yes they do work, and yes they are dangerous and have many negative side effects.Yes they do work, and yes they are dangerous and have many negative side effects.
Is 9v dc in positive or negative?
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 color is green positive or negative for DC?
green is ground regardless of ac or dc
Which is more dangerous ac or DC shock?
DC is more dangerous because its magnitude doen't goes zero instantly after every half cycle as in case of AC .
What is negative 48 volt DC voltage?
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
Was Washington DC named most dangerous city in 2009?
no
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.
Why ac current is more dangerous than dc?
no actually dc current is more dangerous than ac because dc is a direct current and has no current zero condition ,which is very dangerous and do not leave us if we get shock while ac current leave us when we get shock
Which type of electrical current, AC or DC, is more dangerous?
Both AC and DC electrical currents can be dangerous, but AC is generally considered to be more dangerous than DC. This is because AC can cause muscles to contract involuntarily, making it harder for a person to let go of a live wire. DC, on the other hand, typically causes a single muscle contraction, making it easier for a person to release the source of the shock.
What is a negative risk?
A negative risk is something that is a bad or dangerous risk to take.
