Can rheostat run on AC current and DC current?
Yes, a rheostat can be used with both AC and DC currents. The rheostat's variable resistor can be adjusted to control the current flowing through a circuit, regardless of whether it is AC or DC.
What are two types of electrical currents?
Direct current (DC) flows in one direction and is commonly used in batteries and electronics. Alternating current (AC) changes direction periodically and is used in homes and most electrical grids for its ability to be easily transmitted over long distances.
What kind of current did Westinghouse advocate?
Westinghouse advocated for alternating current (AC) as opposed to direct current (DC). He believed that AC was more efficient for transmitting electricity over long distances and ultimately won the “War of Currents” against Thomas Edison, who supported DC.
What are the 2 basic types of currents?
The main division is between alternating current (AC) and direct current (DC). AC is universal now for domestic and industrial supply, but DC used to be used in some places in the early part of last century. Automobiles use DC at 12V which is I think universal now. AC in domestic use can be at 50Hz (Europe and many other places) or 60Hz (North America), and can be at either 240V or 120V.
Does a light switch produce AC or DC electric currents?
Alternating (AC) and direct (DC) currents are different forms of electricity. It is universal nowadays to have AC in all houses because the electricity grid distribution system is all AC. DC was used by Edison and continued for some years but is now discontinued. It is still used in vehicles where 12 V DC is the normal system. A light switch simply interrupts the current or makes the circuit as required, and both AC and DC need to have switches.
What is the definition of AC-DC converter?
AC-DC converter such as a convertor by which we can convert alternative currents into direct current & its vice-versa. ...... anil allahabadi
Does the galvanometer measures AC and DC current?
It is used to detect very small DC currents only. For AC signals Detectors are used.
For a 3 phase alternator why there is an AC voltage generated in the absence DC excitation?
due to residual magnetism
Skin effect related to ac and DC?
IT IS RELATED TO AC ONLY BKZ SKIN EFFECT DEPENDS FREQUENCY ONLY WHERE IS IN DC NO FREQUENCY
Can rheostat run on AC current and DC current?
Yes, a rheostat can be used with both AC and DC currents. The rheostat's variable resistor can be adjusted to control the current flowing through a circuit, regardless of whether it is AC or DC.
Does electrical transformer use a DC or AC source?
A transformer is a device to convert high voltage AC to low voltage AC & vice-versa. It works on the principle of induction. Since induction occurs only in an AC supply, a transformer cannot work on DC.. So, it is not possible to convert DC supply to AC using transformer. You would need an inverter to convert DC to AC.
What kind of current used in train?
Trains use DC currents! It's predominantly AC now but more dc in the early days. Both still in use. See DC and AC section below article-
What happeend if armature is connected to transformer?
its typical question experimental results would give sound results yet i'l give you explanation though you feed a dc supply to an armature, still ac currents will flow in the armature. this is caused by the rotation of armature while providng DC current through stationay brushes. if you connect it with a transformer ( AC), then it might experience DC currents flowing in the coil. so, initially it'l experience a movement and then it may clogg or magnetic locking, since, field is DC and armature is also DC. while armature is designed for ac currents, it may overheated by dc currents
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 are two types of electrical currents?
Direct current (DC) flows in one direction and is commonly used in batteries and electronics. Alternating current (AC) changes direction periodically and is used in homes and most electrical grids for its ability to be easily transmitted over long distances.
How are eddy currents related to DC Generators?
i don't know......sorry =)
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
