relay and vacuum tube are the electronics devices which are invented firstly in the field of electronics.
but they are not revolutionary as transistor which was discovered by John Bardeen.after that other devices are invented like fet mosfet and after that digital devices was invented with the help of these devices.

How do you calculation uncertainty of an electronic balance?
the least count of the device must be noted first. the uncertainty of this will be the least count divided by 2. so if its is 0.1 then it will be 0.05
In which state was the electronic voting machine first introduced in India?

How are electronic volumes measured?
electronic volume can be measured by using transducer transducer is a device which convert non electrical signal to electrical signal. First you need a microphone which is a transducer after that apply the sound vibration on this microphone it will produce a voltage the voltage is directly proportional to applied sound volume level. it measure in decibel.

Not all electronic devices are computer, discuss In details?
First you need to able to distinguish between electronic device and and computerize device. Electronic devices are device that needs power source (electricity) for operation. While a computer is an electronic device that accept data, process data and give an output base on the received input. Not all electronic devices are computer with the below key points. A computer have input unit, processing and output unit which other electronic devices do not have this features. A computer must be able to accept instructions, eg your mobile phones, calculators can accept instructions so they are computer because they have an input method. While an electronic device does not have any input method like your radio. You radio only need a power source to transmit sounds via electromagnetic waves, it doesn't have input, output nor processing unit
