Electromagnetism Generator

February 10, 2010

A simple generator is similar to an electric motor.
With a motor, we put electrical energy in and get rotational energy out,
with a generator we put rotational energy in and get electrical energy out.

As with the motor, the current direction changes
with each half turn of the generator.
The generator produces alternating current
because slip rings are used in place of a split - ring commutator.

The slip rings keep a continuous connection
with the wire around the armature (continued).

If a simple electric motor with a split - ring commutator
is used to generate electricity, you do not get alternating current.
A different type of electrical output is produced.

First Conditional: real possibility

We are talking about the future. We are thinking about a particular condition or situation in the future, and the result of this condition. There is a real possibility that this condition will happen. For example, it is morning. You are at home. You plan to play tennis this afternoon. But there are some clouds in the sky. Imagine that it rains. What will you do?

IF	condition	result

It is a practical guideline to ethical and mental development with the goal of freeing the individual from attachments and delusions; and it finally leads to understanding the truth about all things. Together with the Four Noble Truths it constitutes the gist of Buddhism. Great emphasis is put on the practical aspect, because it is only through practice that one can attain a higher le...

Exponential function

January 4, 2010

In mathematics, the exponential function is the function e^x, where e is the number (approximately 2.718281828) such that the function e^x equals its own derivative. The exponential function is used to model phenomena when a constant change in the independent variable gives the same proportional change (increase or decrease) in the dependent variable. The exponential function is also often written as exp(x), especially when x is an expression complicated enough to make typesetting it as an ...

The Cell Cycle & Mitosis

December 21, 2009

What is (and is not) mitosis?

Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase.

Muscular System

December 21, 2009

Over 600 skeletal muscles function for body movement through contraction and relaxation of voluntary, striated muscle fibers. These muscles are attached to bones, and are typically under conscious control for locomotion, facial expressions, posture, and other body movements. Muscles account for approximately 40 percent of body weight. The metabolism that occurs in this large mass-produces heat essential for the maintenance of body temperature.
