Field-Effect Transistors and Op-Amp Principles
Construction and Working of an n-channel JFET
Construction
An n-channel JFET consists of a small bar of extrinsic n-type semiconductor material. Two ohmic contacts are made at its ends, serving as the drain (D) and source (S) terminals. Heavily doped p-type electrodes form reverse-biased p-n junctions on both sides of the n-type bar, creating the gate (G) terminals (usually connected together). The thin region between these two p-gates is the n-channel, through which current flows.
Working
The gate-

Principles of Effective Office Management and Administration
Strategic Factors for Choosing an Office Location
Office location refers to the geographical place where an organization sets up its administrative and managerial activities. It is the physical site from which office work such as planning, coordination, communication, record-keeping, and decision-making is carried out. A suitable office location plays a very important role in the smooth functioning of an organization because it directly affects efficiency, cost, employee satisfaction, and the organization’s

Animal Farm Chapters 6–10: Power and Corruption
Chapter 6
The animals work harder than ever to build the windmill, and Napoleon begins trading with neighboring farms, breaking one of the original commandments. The pigs move into the farmhouse and enjoy luxuries, justifying it as necessary for leadership. When the windmill is destroyed in a storm, Napoleon blames Snowball and uses it to increase fear and control.
Chapter 7
The animals suffer from hunger and harsh conditions. To hide the food shortage, Napoleon uses Mr. Whymper to spread false reports.

Lists
Ordered (different from sorted) and linear.
Duplicates allowed.
Implementation: Array list: good for iteration, resizable; add = slide to right, remove = slide to left to close gap. Linked list: nodes & pointers, no shifting, grows dynamically, good for lots of insertions/deletions.
Core operations: add(newEntry), add(pos, newEntry), remove(pos, newEntry), replace(pos, newEntry), getEntry(pos), contains(entry), toArray(), getLength – numberOfEntries, isEmpty(), clear(). Helper methods: ensureCapacity,
Geography Fundamentals: Physical and Atmospheric Concepts
Physical vs Human Geography
Physical Geography focuses on natural systems & processes (weather, climate, landforms). Human Geography focuses on culture, population, and cities.
Atmospheric Structure
- Pressure & density decrease with height.
- Temperature pattern by layer:
- Troposphere: $\downarrow$
- Stratosphere: $\uparrow$
- Mesosphere: $\downarrow$
- Thermosphere: $\uparrow$
- Inversion: Temperature increases with height in a layer.
- Temperature $\uparrow$ means molecules move faster.
Maps & Coordinates

Form of Transmission
Often dwells in the pharynx or nasopharynx of healthy people. Spreads to the lungs, sinuses, ears, and meninges. It is common in children, adults living with them, and people with low levels of protective antibodies against the pneumococcus. It spreads easily from person to person through droplets of saliva. Diffusivity increases during
