each time‚ the unknown resistance was approximately equal to the Ohm’s of the resistor‚ therefore confirming Ohm’s Law. An ammeter is connected in series because its purpose is to measure the current in the circuit‚ and since it is a low impedance device‚ connecting it in series would cause a short circuit‚ damaging the ammeter. Whereas the voltmeters purpose is to measure the electrical potential difference between two points in the circuit. The potential difference

The relationships between plant reproduction and human reproduction are that they both create an egg. There are feminine and masculine parts wanted in both progressions. Both produce descendants by sexual reproduction. The change among plant reproduction and human reproduction include that in pinnacle plants you have to plant the seed before it will develop into whatsoever‚ and in human reproduction you do not have to plant the seed it take a long procedure. Flowering plants create many more offspring

schizophrenia. Variations from the arrangement of the nervous system and abnormal changes in the cerebrum are in fact‚ the reasons for the disorder. The nervous system abnormalities lie in the wrong arrangement of contacts between nerve cells and the impedance of neuronal migration amid intrauterine improvement and the main months of life (Van Haren et al.‚ 2008). Nerve cells that did not possess an appropriate place in the brain and did not establish the vital contacts with different cells‚ in the long

Chapter (9) Single-Phase Motors Introduction As the name suggests‚ these motors are used on single-phase supply. Singlephase motors are the most familiar of all electric motors because they are extensively used in home appliances‚ shops‚ offices etc. It is true that singlephase motors are less efficient substitute for 3-phase motors but 3-phase power is normally not available except in large commercial and industrial establishments. Since electric power was originally generated and distributed
