In relation to a/c mains electricity, or to audio frequencies, 400 kHz is very high. In relation to radio waves it is fairly low.
How does a transformer look like?
They are made in a large variety of types. Some of these are shown in the linked article.
How can you identify which one is step up or step down transformer?
A transformer has two windings, termed the 'primary winding' and the 'secondary winding'. The primary winding is the winding connected to the supply, while the secondary winding is connected to the load.
The secondary voltage of a 'step up' transformer is higher than the primary voltage; the secondary voltage of a 'step down' transformer is lower than the primary voltage.
The simplest way to determine whether a transformer is a step up or step down, is to measure the primary and secondary voltages. If you are simply looking at a transformer, then the transformer's insulated bushings will give you a clue -the higher voltage bushings are much bigger than the lower voltage bushings. If you have access to the inside of the transformer, then the higher voltage windings are thinner and have a greater number of turns than the lower-voltage winding.
What is resin impregnation process?
In resin impregnation, any porous material is made impervious by filling its pores with the resin.
What is the purpose of boiler drum?
Purpose of the boiler drum is to collect steam from all the various tubes in a boiler, and send it to the turbine to spin the generator
How a Cathode Ray Oscilloscope is used to measure Alternating current?
An oscilloscope is, essentially, a voltmeter -it measures current by measuring the voltage drop caused by that current across a standard resistance.

Why is short bead in welding on mild steel and high tensile steel are to be avoided?
Short bead as well as arc strikes create a sudden localized temperature increase to the metal and can cause cracking.
What is the load rejection and load pick-up in the power generation?
Load rejection occurs when load is suddenly removed from the generator. The most obvious example of this is the breaker connecting the generator to the power grid opens. This results in a full load rejection.
Load pick up means the generator is supplying power to a given load. When a generator comes on line, it will pick up some load that might have been supplied by another generator.
What is an h stamp on a boiler?
American society of mechanical engineers has a classification of pressure vessels. Certain type of the boilers have H stamp according their classification, and this stamp is required by local authorities in order to get boiler approved for installation.
How would you calculate the admittance if you were given impedance?
To calculate the admittance if you are given the impedance, you take the inverse of the impedance ( that is 1/z).
Cable schedules provided a tabulated list of all cables with relevant details such as cable number, cable type, size and rating, voltage, number of cores and length of route. Cable schedules are applicable for power cables, control cables, instrumentation cables and industrial data communication cables. In addition to the cable schedules, termination diagrams are provided for use by the electrical installation contractor.
How much horsepower and torque does a 1978 Olds 350 Rocket have?
Chiltons manual says 170 horsepower and 275 ft.-lbs. of torque.
What are examples of Bending Force?
A good example of Bending Force would be a beam or a pillar. Also a rubber band or elastic.
I hope this helped,
M.M.
What is jigging in galvanizing?
jigging is the name of the process of hanging items on a wire prior to suspending into molten zinc to galvanize the steel
Calibration is required to maintain the accuracy and reliability of instruments.
What is the density of steel as per IS 2062?
The density of steel as per IS 2062 will vary. This is because steel's density typically changes with composition.
Who is the father of industrial engineering?
the father of industrial engineering is FREDERICK WINSLOW TAYLOR
Which material will the Sun heat up fastest?
SIMOCODE is a motor management system provided by SEIMENS, which helps to circuit overload protection, control & communication capabilities in a single package for motors. Currently it has two type that is SIMOCODE pro C & SIMOCODE pro V. SIMOCODE pro V is more advance & it use for more complex applications. Another features of SIMOCODE pro motor management system is the amount of information that can be monitored, collected & communicated, high degree of details on status & performance of each motor load is possible by using this.
