### In what unit is current measured?

Electrical currents are measured in a unit called amperes, which
are abbreviated as "amps." There are two different designations
that measure currents: direct currents (DC) and alternating
currents (AC). Amperes are coulombs per second. Amperes are
electrical current units that are part of the meter-kilogram-second
system. A flow of one coulomb per second is equivalent to one
single ampere.

### What is the CGS unit of current in the electromagnetic system equivalent to 10 amperes?

The centimetre-gram-second system (abbreviated CGS or
cgs) is a metric system of physical units based on centimetre
as the unit of length, gram as a unit of mass, and second as a unit
of time. All CGS mechanical units are unambiguously derived from
these three base units, but there are several different ways of
extending the CGS system to cover electromagnetism.
CGS approach to electromagnetic units The conversion
factors relating electromagnetic units in the CGS and SI systems
are much more involved - so much so that formulas for physical laws
of electromagnetism are adjusted depending on what system of units
one uses. refer to link below for methods

### What is meant by energy meter having ct ratio - 5?

A CT, or current transformer, has a specified current ratio. The
5 in your question is the current supplied to the metering
instrument at full scale. CT's current ratio is always full scale
to 5, for instance - 200:5, 3000:5, etc.
So, if a CT has a ratio of, say, 1000:5, this means when the
conductor being measured is supplying 1000 amperes to the load, the
CT will output 5 amperes to the instrumentation. The relationship
is linear, so if the current is 500 amperes, the output will be 2.5
amperes, at 200 amperes the output will be 1 ampere, etc.
This is done so the instrument can be designed always the same,
with a 5 ampere input, no matter what size current is to be
measured. Otherwise you would have to order (and manufacture) many
different models of meter, one for each current range.
The metering must be set, or programmed, with the CT multiplier,
so it knows how much current is really flowing when it sees 5
amperes on the input.
Similarly, we use PT's or potential transformers to reduce
higher system voltages to a range that the instrument
can also handle.

### What do you mean by fault MVA?

This describes what is known as the 'fault level' at a
particular point in an electricity transmission or distribution
system, expressed in megavolt amperes, enabling the theoretical
value of fault current to be calculated at that point in the
system, in order to ensure that the relevant switchgear is capable
of interrupting that level of fault current.

### What is term used when an Alternating current acts like a direct current?

Perhaps you are asking how the voltage of alternating current is
measured, to be equivalent to the voltage of a direct current
system.
Alternating current and direct current have distinct properties.
With direct current, voltage is at a constant polarity, and a
direct current voltage source will maintain a uniform, constant
voltage level. Alternating current reverses polarity at a given
frequency and therefore it's voltage continuously varies from a
positive peak voltage level, through zero, to a negative peak
voltage level, repeating this cycle continuously. For this reason,
voltage of an alternating current system, is measured in
root-mean-square (rms), which is a voltage, which when multiplied
by the current in amperes, calculates power which is equivalent to
that of direct current of the same voltage and current values.
With a typical sinusoidal waveform, the peak voltage of
alternating current is divided by the square root of 2 to determine
the rms voltage. The 120 volts output in the wall outlet in our
home is actually about 170 peak volts.

### How many volts are in 600 watts?

You are confusing electrical potential (Volts) and power
(Watts).
The equation for power (watts) is P = VI where V is volts (a
measure of electrical "pressure") and I is current in amperes (the
rate of flow of electricity).
If the system is 120V and the power used is 600W then the
current used is 5A.
If the system is 240V and the power used is 600W then the
current used is 2.5A.

### What energy conversion take place in a stereo?

A stereo is a simpler version of today's home audio system or a
home theater system. In the past, a stereo was unified audio
component (box) that did everything starting with receiving and
tuning the AM, FM, etc. signals, to finally outputting them to
connected speakers.
The basics of a "stereo" system is that it takes electromagnetic
power (current, either AC or DC) to power itself and its internal
amplifiers and tuners. The tuner that's selected (AM, FM, etc) then
takes any electromagnetic energy (radio waves) collected by the
antenna, and both tunes (selects) a specific frequency band and
amplifies that band. At this point, the electromagnetic energy
(radio waves) have been converted to another form of
electromagnetic energy (current).
This current (tuned frequency signal) is IF-subtracted /
demodulated, and eventually converted to another current
representing an amplitude-significant signal. This AM signal
(current) is fed to another amplifier, and then piped to the
speaker(s).
The speakers convert the electromagnetic energy (current) that's
fed to them into mechanical energy that pushes on the speaker's
surfaces. The speaker converts this mechanical energy (motion) into
audio distortions in the air/atmosphere which we call sound
(pressure).
So, conversions are:
electromagnetic energy (radio waves)
\/
electromagnetic energy (current)
\/
mechanical energy (speaker motion)
\/
mechanical energy (air pressure)

### Is a voltage and current source the same thing?

Yes they are the same thing!
***********************
They are certainly not the same thing.
Voltage, or e.m.f. (electromotive force), is the cause of
current.
A common analogy is that voltage is similar to pressure in a
hydraulic system, while current is the volume of flow which results
from a given voltage. In a hydraulic system it might be, for
instance, in gallons or litres per second. In electricity it is
coulombs per second and is given the name amperes, abbreviated to
the upper case A.

### What is reactive power in electrical system?

It is product of Current,Voltage and Sin angle between current
and voltage.
Reactive Power = Current(I)*Voltage(V)*Sin(angle B/W
Voltage and Current)
It is also know as the power used in transformation of energy in
one form to another form.
Answer
Reactive power is the rate at which energy is alternately
stored in a magnetic or electric field and returned to the supply
of an AC circuit, and is expressed in reactive volt amperes.
Reactive power is associated with inductive or capacitive loads.
The vector sum of reactive power and true power (watts) is
called the apparent power (volt amperes) of the circuit.

###### Asked in Heating Ventilating and Air Conditioning

### What are the benefits of a 240 volt appliance?

If you needed to perform the same amount of work with 120 volts,
you would need twice as much current. For example, a room air
conditioner using 240V might use 8 amperes of current. If you
cooled the same room with an A/C unit running on 120V, it would
take 16 amperes of current (actually a little more because of
reduced efficiency). That means your wiring will need to be larger
to safely deliver the additional current to the outlet. You would
also need an outlet that is rated to safely carry the higher
current. In countries where 200-240 volts is normal, the entire
electrical delivery system can be smaller and cheaper because of
the overall reduction in current demand.

###### Asked in Electronics Engineering, Electrical Engineering, The Difference Between

### Difference between voltage and current?

Voltage is electrical potential, measure in derived units of
volts, which is joules per coulomb. Current is electrical flow,
measured in derived units of amperes, which is coulombs per second.
Stated in other terms, voltage is energy per charge, while current
is charge per time. That makes power, or watts, equal to energy
per time, and that is joules per second.
If you think of the water system analogy, volts is sort of
similar to pounds per square inch (though not completely so), while
amperes is similar to gallons per minute.
Answer
Voltage is synonymous with 'potential difference'
-not potential- measured in volts. Current is the flow of
electrical charge, measured in amperes. The volt is an SI derived
unit, wheras an ampere is an SI base unit.
