Lesson 40 of science

We are learning about batteries this week in science. Batteries are Electrochemical devices. The chemical energy in a battery is converted into electricity. Chemical reactions occur within a battery. Through these reactions, electricity is generated. Batteries can be classified into the following types: Alkaline batteries which are very popular Nickel-cadmium these are very good forContinue reading “Lesson 40 of science”

Lesson 35 of science

This week’s science lesson introduced us to the concept of a robot. In order to be true robots, they must be able to function autonomously, without human operators. The science of robotics consists of designing and building such machines. Making a robot does not require genius. You just need creativity, diligence, curiosity, and patience. MakingContinue reading “Lesson 35 of science”

Lesson 30 of science

Amateur radio (ham radio) was the topic of this week’s lesson. Ham radio is noncommercial radio communication. Radio waves are used to communicate between two people. The use of ham radios for training is sometimes needed to learn how to use a radio or electronics. Experiments can also be conducted using the radios. They canContinue reading “Lesson 30 of science”

Lesson 25 of science

Whenever you speak into a radio, the audio waves that come from your mouth are converted into electric current. The carrier wave then becomes modulated. This modulated carrier wave can then be amplified depending on the reserve. As a result of the antenna signal, electrons oscillate back and forth, which produces magnetic and electric fields.Continue reading “Lesson 25 of science”

Lesson 20 of science

   This week I learned about soldering. According to the American Heritage dictionary the definition of soldering is a , “fusible alloy used for joining or binding together metal surfaces or joints, as the edges of tin cans, jewelry, and kitchen utensils.” The more wattage you have the more heat that is produced to uniteContinue reading “Lesson 20 of science”

Lesson 15 of science 

The transistor is one of the most important things that has ever been invented. It amplifies   it switches  it stores  There are three terminals: The Source, the gate and the drain. According to Convention the flow of energy goes from the positive charge to the negative charge. It actually goes from the negative charge toContinue reading “Lesson 15 of science “

Lesson 10 :Electronic Components and Theories

Electronic component control electrons in specific ways. Electronic components have two or more leads or terminals. Terminals Connect into a printed circuit board or a (PCB). The placement of the components is determined by the purpose of the circuit. Atoms are basically building blocks of matter. Adams (  atomos) means invisible. Atoms are made ofContinue reading “Lesson 10 :Electronic Components and Theories”
