Current is the flow of electrons in a system usually taught from positive to ground or zero potential. It is defined by the formula current = voltage/resistance Everything has resistance - even wire.
the flow of electrons in semi conductor is called electric current. the electrons revolved around the nucleas is called free electrons
Yes, alcohol is a liquid and has delocalised electrons which can carry the electrical current. Edited: Seriously? Unless there are impurities in the alcohol that are electrolytes, alcohol will NOT conduct an electric current. Alcohols are considered as NON ELECTROLYTES, as they do not ionize and thus will not conduct a current. (Dr.J.)
Yes, an electric current is the flow of charged particles.
DC current
The opposite of an electric current is the absence of an electric current, meaning no flow of electric charge through a conductor.
A current.
Electromagnets have temporary nature because if you take away their electric current, the magnet no longer works.
Excessive current can be in the connection of many devices into a single socket.this may cause overload in the circuit
Electric current carries electric charge. Actually to say it in the right sense, we have to say that electric current is the rate of flow of electric charges
The flow of electric charges is current.
ampere
It is called an electric current.
