A 50 Hz single-phase transformer has a turn ratio of 6. The resistances are 0.9 ohms and 0.03 ohms and
reactances are 52 and 0.13 12 for high voltage and low voltage windings respectively. Find (i) the
voltage to be applied to the high voltage to obtain full-load current of 200 A in the low voltage
winding on short circuit and (ii) the power factor on short circuit.

Biologists recognize five levels of cell organization. the lowest and simplest is the cellular level. organisms here are either unicellular organisms, like protozoa, or colonial organisms. colonial organisms are composed of single-celled individuals that stay together to sustain the life of the whole colony. next on the scale of complexity is the level occupied by tissue. a tissue is a group of similar cells which perform a similar activity. tissues that are organized around a common function together make up an organ, the third level of complexity. the fourth level of organization is the system, formed by a group of organs which together perform a specific bodily process. the fifth and highest level is the organism level, in which body systems work together in a structure capable of independent life. main idea:
