Essay On Passive Components

1652 Words7 Pages

Passive Components Definition: A passive component is an electrical device that does not require energy to operate, except the alternating current (AC)/direct current (DC) circuit that passive component is connected to. A passive component is not able to increase power up and amplifying signal. Passive Components: Passive component would be: 1. Inductor 2. Resistor 3. Capacitor 4. Transformer Passive components may be linear or non-linear. Generally, passive components do not increase the power of a signal nor are they able to amplify it. .The most of the passive components which have two terminals are usually defined as a two-port, which is an electric circuit that has two pairs of terminals attached together by an electric …show more content…

• Its power is mostly calculated in Watt. Types: • Carbon resistors • Film resistors • Wire wound resistors Resistor Networks: • They either can be connected in series or parallel combinations to form a network of resistors which can act as voltage droppers, they can also be used as voltage dividers and another use of these networks of resistors is: they are used as current limiters. • Power rating of a resistor is a physical property that depends on their size or their construction on the other hand. Physical size is directly proportional to power rating because it increases every time we increase the size of resistor. Applications: • The way, resistors work is very useful because they can be used in the heating elements in many electronic devices like toasters, heaters, electric stove, hair dryers etc. because they evolve heat as voltage. • Variable resistors are also very valuable because they function as sensors, switches and voltage dividers as well. • As we all know, many electrical devices are based on electrical resistance and Ohm’s law. • Light bulb, polygraph, fuse, voltmeter are some important applications of

    Using the data provided in each one of these tests it can be assumed that one has done the steps to be able to determine the magnitude and orientation of the charges of the tape in each test, thus, allowing them to apply the same principle to any object they so desired. Their results would line up with the following; that if the two pieces of tape are torn from the same 40 centimeter strip then the tops of both pieces of tape would be positive and the bottoms of both pieces of tape would be negative and that if they would double the tape the attraction or repulsion in general would lower due to the increased density. Their data would also show that two pieces of tape ripped from each other would result in one piece being entirely positive and the other being entirely negative, they would also be able to state that the orientation of how the tape is paired up doesn’t matter.

    P4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons. Perimysium surrounds a bundle of muscle fibres, it is a casing of connective tissue.

    In this essay I will write about the strengths and weaknesses of perception as a way of knowing. Perception is the way we perceive the world through our senses. We use all five of our senses, which are sight, hearing, smell, taste and touch to understand the world and interpret it. We can then say it’s a Primary way of knowledge. We can also say that, because the senses is the way our body communicates, we have at least three more senses: kinesthetic sense, which is our awareness of our body’s dimensions and movement; vestibular sense, which is the awareness of the human’s balance and spacial orientation; and organic sense, which is the manifest of the internal organs (for example, hunger or thirst).
