Kaustubh KatdareFirst of all, please provide attention to the titles of your post. 'basics' makes no sense and I hope you will agree that the title I've updated makes more sense. Also, fix the CAPS LOCK key on your keyboard, it seems to be broken.
Current is a general characteristic of electricity, like voltage and resistance. It's a name given to the flow of electrons (charge) through a medium. Electricity is a generic name that's used for the common flow of energy to power all the electric stuff. -
Ramani AswathCurrent in general refers to any flow. Thermal currents, currents in a river and also electric currents.
Electricity deals with charges on ions, electrons and their movement. -
Jeffrey ArulrajElectricity is flow of power in the electrons state
Current in general is flow of power in any form -

if electricity it is flow of electrons then what is thundering?bioramaniCurrent in general refers to any flow. Thermal currents, currents in a river and also electric currents.

It's still the electrons.tarun goelif electricity it is flow of electrons then what is thundering? -

Electrons in free air?The_Big_KIt's still the electrons. -
Jeffrey Arulraj
yes Why are there no atoms in air ??tarun goelElectrons in free air?
If atoms are present electrons are present -
Ramani Aswath
Well, they need not be free electrons but charged water particles (droplets) and air molecules. When the static charge exceeds the breakdown voltage between the source (clouds) and sink ground, another cloud or other there is a discharge. The violent discharge causes the air in the path to expand and rush away creating a vacuum. After the flash ends the air rushes back with a clap, which we call thunder.tarun goelElectrons in free air? -
aruncharythunder is a heavy and weighted electronic composition ,when it fall on the ground simply it creates drill like structure...its may be in many time bigger then magawatt power.................

Thunder is just the sound. It does not do any damage except to ear drums if too near.aruncharythunder is a heavy and weighted electronic composition ,when it fall on the ground simply it creates drill like structure...its may be in many time bigger then magawatt power.................
Lightning can damage. It is a static discharge of mega proportions. It need not always strike the ground. More often it is between clouds carrying opposite charges. Lightning strikes the highest point on the ground which is tops of buildings and trees and such. Rarely it hits the ground. It does strike the ground if there are conducting minerals or metal ore. -
Jeffrey ArulrajHello here thunder causes near vaccum state due to very high amount of charge passage in less time period this causes all the disturbances
Read bioSir's post that explains the effect more clearly -
Henrialthough the two terms might seem almost similar,they are not.Whereas electricity refers to the flow of energy in form of electrons,current refers to the flow of energy in any form from say thermal to electric.So,yeah...in as much as the defination of electricity can be substituted for current,,there is a slight difference
-
Henrithundering refers to the sound produced when there is neutralisation of positive and negative ions within the atmosphere...so thunder can never be electrons whatsoever

grsalviCEans the flow of charged ions can be also responsible for electric current , right ?
In case of lightning there are free electrons but also a majority of charged ions of air ,water ,etc. -
Jeffrey ArulrajBut the current due to them is always less as the mobility is inhibited cos of their size
-
grsalviCharged ions charges similar to free electrons ( After all the birth of free electron and charged ion is a same incident ).
Now mobility ,off course its less in solids but what if its in gases(air in lightning ) and liquids (electrolytic process in batteries ) ? -
Jeffrey ArulrajNot real significance due to neighbouring atoms Can contribute very less current only
-
subaBEwhen this static voltage may increasing for causing thunder?it have any specific limits?
-
Jeffrey Arulraj
The static voltage must exceed the ionising voltage of air through the entire distance it has to travel from the sky to the surface of the earth Lightning occurssubaBEwhen this static voltage may increasing for causing thunder?it have any specific limits?
It does not have a fixed value. It must be over 1kV -
YournishedElectricity is a very general term used do describe current and voltage, the fields they produce, and other effects like induction, charge, capacitance, resistance...etc.Current is a term to describe the physical movement of electrons through a material.Voltage is energy. It is the force or charge applied to incite the movement of the electrons.

Have you tried referring to basic physics books? If not, try searching the Internet and let us know what you discover.Ayush LabhWhat's the diff. Between current electricity and electric current ? -

Anyway, you're not the only one with this question. This question has been asked before : Difference between current & electricity? . I will merge the discussions later.Ayush LabhWhat's the diff. Between current electricity and electric current ?
