Question

What are electrons and how are they involved in creating and electric current?

Answer 1

Electrons are negative charges.

Current is the change in charge per unit time

So current is a rate of change during a finite interval of time.

Answer 2

Mathematcially, current, I is
$$
I = \cfrac{dq}{dt}
$$
where q is charge (Coulombs) and t is time .

Units of current are in Amperes

Answer 3

Note that 1 Coulomb is a horrendously large unit of charge equal to \(6.2415 (10)^{18}\) electrons

A change of 1 Coulomb of charge in 1 second is equal to 1 Ampere

A typical household circuit can only handle about 12 Amperes of current before the circuit breaker trips. So just 12 Coulombs of charge in 1 second is enough to trip the breaker.
