A) A single-phase, 50Hz, 100kVA, 2400/240V transformer has no-load current of 0.64A and core loss of 700 W, when its high voltage (HV) side is energized at rated voltage and
frequency. (i) Calculate the two components of the no-load current. (ii) If this transformer
supplies a load current of 40A at 0.8 lagging p. f. on its low voltage side, determine the
primary current and its power factor. Ignore the resistance and leakage reactance drops
for the transformer.

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
