Document Summary

Objectives: to investigate an ac capacitive circuit, to investigate the impedance of a capacitor and see how this varies with frequency. Capacitor is another fundamental electrical element having two conducting surfaces separated by an insulating material and having a capacity to store charge on its plates. A measure of capacitor"s ability to store charge is capacitance. A perfect capacitor in an ac circuit takes a current that leads the impressed emf by exactly. Storing and releasing equal amount of electrostatic energy during successive quarter cycles, the average energy per cycle involved in such a circuit is zero; this means that the average power delivered to a capacitor is zero. Capacitive reactance is the opposition to the flow of charge, which results in the continuous interchange of energy between the source and the electric field of the capacitor. The capacitor"s reactance is also called inpedance and is measured in ohms. and phasor diagrams showing the phase relationship.

The following three impedances are connected in series across a 40 V, 20 kHz supply: a
resistance of 8 Ω, a coil of inductance 130 μH and 5 Ω resistance, and a 10 Ω resistor in
series with a 0.25 µF capacitor. Sketch a neat diagram representing this network, and
calculate:
5.1.1 The inductive and capacitive reactance’s. (4)
5.1.2 The magnitude and phase angle of the circuit impedance. (4)
5.1.3 The voltage drops across resistance, inductance and capacitance.

Elements of Gothic Fiction

1- Settings that often include large, drafty old houses that have "been in the family for years"

2- An atmosphere of mystery and suspense that is enhanced by a plot containing secrets

3- A ghostly legend, an unexplainable occurrence, or a story about a horrible death or murder

4- Omens, foreshadowing, and dreams (bad dreams about something bad that is going to happen) play a role in the mysterious air of the. story

5- Highly charged emotional states like: terror, the brink of insanity, anger, impending doom, and obsessive love

6- Supernatural events: ghosts, unexplained sounds, etc.

7- Damsels in distress are frequent (sometimes to be rescued; sometimes not to be rescued)

8- Words designed to evoke images of gloom and doom. (The good gothic writer can make you) picture the scary scene he is trying to create in your mind.)

9- The death of a man or woman in the throes of some great passion, the obsessive nature of a man or woman in love, or excessive grief one\} feels upon the loss of a loved one

American Gothic writers are sometimes referred to as "Brooding Romantics" or "Anti-transcendentalists" because, unlike the optimism of the Transcendentalist writers, they

A. had poor health and were always depressed.

B. explored the human capacity for evil.

C wrote about the good and bad aspects of nature.
