Yes, you can use both, but watts is more useful; it provides the total amount of power the generator can output.

by using dc volts across pairs and with an analog meter to check the deflection of the needle to determine if they are in phase

1.8 kilowatts = 2.4 hp

<<>>

The conversion is 746 watts are equal to 1 horsepower. To change 1.8 kilowatts to watts is 1.8 x 1000 = 1800 watts. Therefore 1800/746 = 2.4 horsepower. This is how the answer above was obtianed.

No, There can't Be current without voltage

resistance

The first statement is true, the motor needs a power source to operate.

A 3-phase motor will not run on single-phase power or if one of the three phases is disconnected. If the motor is not running, there is no back-EMF generated in the coils, and they draw excessive current, thus overheating.

I think your are asking about the working principle of a pneumatic transmitter. (not transmeter) A pneumatic transmitter measures liquds or air temperatures over a given range-usually a 200 degree temperature range. The range, selected for its purpose could be -40 to +160 or 0 to 200 -as in the case of Honeywell or even 100 deg. ranges, as in the case of say-Johnson Controls. (0-100) Aside from temperature range, the other important criteria is the output of the transmitter. In the case of commercial controls, the correlation of 200 degree temperatures (which is 201 values, not 200) occurs over a pressure span/output of 3 to 15 pounds.(13 values) For example, in the case of a 200 degree transmitter of say 0 to 200 degrees, the zero temperature value output equates to a 3 psi signal. At 200 degrees, the top of the range, the transmitter would output a 15 psi signal. In other words every degree change up from zero degrees would account for a pressure increase (rounded)of .064 psi. (13 pounds divided by 201 degrees)=.0646766) Pneumatic transmitters are typically direct acting and are one-pipe constant bleed devices. Their working principle involves movement of a flapper a given distance in direct response to the sensed temperature acting upon it. As the temperature rises, the bleed port positions itself toward a closed position which allows less air to escape to atmosphere. Less air to atmosphere dictates more air building up in the air line. This value is then transmitted/measured by the controller-which is pneumatically attached to the transmitter.

There no brushes in an induction motor. The rotor is independent and is a short-circuited cage of parallel bars.

Kilovolt = 1000 volts.

Objects that conduct electricity poorly are called poor conductors of electricity or insulators . There is a difference though. Poor conductors of electricity are capable of conduction under certain circumstances while insulators cannot conduct electricity under any condition, example ; air is a poor conductor of electricity as it cannot conduct under normal conditions but lightning is able to pass through it during a storm.

A transformer is a static device which converts electrical energy from one circuit to another circuit without changing frequency, power, power factor.

It works on the principle of faradays laws of electro magnetic induction.

Yes, that is exactly the way they service high-tension lines: they are deposited from helicopters, attach themselves directly to the power line and work from there! As long as they do not touch another line or anything that is "grounded" (connected to earth), they are fine, as they do not form a "circuit".

=================================

Linemen are not 'deposited from helicopters'.

They are lifted from the ground in the 'bucket' of a so-called 'cherry picker' truck,

insulated from the ground by its tires. A ring of warning cones is placed around the

truck, and man-carrying bucket is then attached to the line. At that point, the

bucket, the man, and the truck are all at the voltage on the line. The man in the

bucket may safely handle the line, and nobody has a problem unless he happens

to be walking by on the ground and decides to catch hold of the truck.,

it is a bad conductor of electricity. i checked it using the tester and the bulb did not glow.

The characteristic of the current sources is that it cannot operate in an pen circuit.

ampere hour is the unit of electricity consumed by electrical load,for example you are consuming 5ampere per hour so unit of power will 5amp-hour,generally unit of power is kilowatthour,so 1000amp-hour =1KWH ampere =voltage/resistance, amp-hour the unit of power on which tariff is calculated for the consumption of electricity

no

A person needs a motor when there is a need for mechanical energy with availability of a power source.

Yes, the minimum is three wires, usually used when the three phases are in balance, with equal currents in all three lines.

In conditions when the three phases might be unbalanced, a neutral wire is added, which makes it a 3-phase 4-wire system, and the current in the neutral depends on how out-of-balance the currents in the three lines are.

the unit of "e.m.f" is "volt"

Audio power amplifiers usually separate the last inductor in the output stage transmission chain. The last inductor usually receives the most attention when it comes to power efficiency in a circuit.

Since circuits experience opposition to current, especially where current is changing direction, capacitive reactance or opposition needs to be balanced with inductive reactance. This is done with the help of an output inductor for maximum output to be reached.

Output inductors are used to dampen circuit resonance with the help of a shunt resistor. This is especially important in high frequency circuits where stability is a real issue.

Power factor is the cosine of the phase angle between voltage and current. In a purely resistive load, like a toaster, since the phase angle is zero, the power factor is 1. In a theoretically purely inductive or capacitive load, with the phase angle at 90 degrees, the power factor is 0. Power factor is also the ratio of apparent power versus true power, or watts versus volt-amperes.

it's just like an GPS System but it's a different type and made from a different com[any.........lolzz
