Question

What causes electric current?

Please answer in your own words.

Answer 1

_____________________


$\huge\text{\underline{Electric\:current:}}$


An electric current is a:


$\sf{\underline{Flow\:of\:electric\:charge\: in\:a\:circuit.}}$


More specifically,


The electric current is the $\bold{\underline{rate\:of}}$ charge flow past a given point in an electric circuit.


Electric current is basically the $\bold{\underline{flow\:of\:electrons.}}$


The higher the energy of the source the higher will be the $\bold{\underline{current.}}$

Answer 2

Answer:

Current is nothing but the rate of flow of electrons i.e. number of electrons flowing through a given cross-section in unit time.

Before understanding the flow of electrons, let us understand about potential.

For example, if two buckets filled with water are placed at different heights and both are connected by a pipe, the water from the bucket kept at a higher place will flow into the bucket at a lower place but the reverse is not possible. This means the bucket at a higher height is at a higher potential while the bucket at a lower height is at a lower potential.
