An ECG (Electrocardiogram), or an EKG (Elektrokardiogramm) works by measuring electrical potential between various points of the body using a galvanometer (a very sensitive voltage meter).
An ECG or EKG machine is a machine that allows the heart to be studied.The machine records the electrical activity with in the heart.ECG means Electyocardiograph
basic electronic is basically a combination of basic electronics component like charge,battery,voltage current, circuit,resistor,ohm's law,power,capacitor,inductor,semiconductor
Computer is an electronic machine not as electronic device rather electronic devices such as Hard Disk Drive, DVD Drive, Keyboard, Mouse constitute components of Computers.
Passive components like capacitors . resistors and coils then there are active components like amplifiers and IC. wires are not electronics anything but just conductors of electrons.
