Why CT is connected in series? CT also need to be connected in series because than only current in the secondary winding will N times the current in primary. CT is to measure the current ( like an ammeter) so it is connected in series with the conductor carrying that current. What happens if CT […]

What is Polar vs nonpolar? Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out. What is an example of a polar bond? Polar bonds are […]

What are biological and environmental factors? Biological factors such as breeding behavior, care of young, time of last eating, and food storage cause changes in daily activity patterns. Similarly, environmental factors such as temperature, snow cover, food supply and disturbance caused by humans in an urban setting also cause changes in daily activity patterns. What […]
