Resistor Color Codes

A resistor is an electrical component that opposes the flow of current. We all have seen different resistors used in the circuits. But have you noticed that there are some colour bands on the resistor? What they indicate? Actually, Resistors are coded are with colours to identify their value and function. There are different resistors depending … Read more

SoftComputing and HardComputing

Electrical Appliance Classes

We use many electrical appliances in our houses, college, offices like a fan, heater, refrigerator, charger, vacuum cleaner, etc. Electrical Appliances are divided into certain classes according to the IEC 61140 standard and used to differentiate between the protective-earth connection requirements of devices. These are Class 0, Class I, Class II, and Class III. Fig. … Read more

Electrocardiography (ECG or EKG)

Electrocardiography is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin. It is abbreviated as (ECG or EKG). A normal ECG is shown below. Fig. 1 Electrocardiograph An electrocardiograph is a machine that is used to perform electrocardiography. Electrocardiogram It is the heart’s … Read more

CardioVascular (Heart) Circulation System

In the previous article, we talked about different body system and their major organs and respective functions. In this article, we will see the anatomy of the heart, working, and functions or CardioVascular (Heart) Circulation System.Blood enters the heart on the right side through two main veins: the superior vena cava and inferior vena cava. Fig. Cardiovascular … Read more

Body Systems and Major Organs

The human body consists of 10 System viz. Skeletal System, Muscular System, Nervous System, Endocrine System, Respiratory System, Cardiovascular system, Lymphovascular system, Digestive System, Excretory System and Reproductive System.       Different organs can work together to perform a common function and works as an integrated unit called organ system or body system.  Body Systems … Read more

Cardiac Conduction System

 In the previous article, we discussed Bioelectric potential, action and resting potential. In this article, we will talk about heart Cardiac Conduction System. A heart has its own electrical system that is responsible for the continuous generation and A heart has its own electrical system that is responsible for the continuous generation and organised transmission of … Read more
