How to describe electric current as the flow of electrons

givi [52]

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma).

Suppose the current in a conductor decreases exponentially with time according to the equation I(t) = I₀ e**(-t / T) , where I₀

Anika [276]

The quantity of charge that passes the point between t = 0 and t = τ is 0.6321I₀τ.
The quantity of charge that passes the point between t = 0 and t = 10τ is 0.99995I₀τ.
The quantity of charge that passes the point between t = 0 and t = ∞ is I₀τ.

<h3>How to determine the charge?</h3>

In an electric field, Euler's number suggest that current starts with a maximum value and decreases to 36.9% of the preceding numerical value in every time interval, τ.

Also, the current in this conductor decreases exponentially with time and as such, it would be used to derive an equation for charge through integration:

I = dQ/dt

dQ = Idt

By integrating, we have this general integral:

Q = ∫dQ = ∫Idt

At an end-time, T, the integral becomes:

$Q = \int\limits^T_0 {I_0e^{\frac{-t}{\tau} } } \, dt$

From time, t = 0 to time, t = T, we would integrate to have:

$Q = \int\limits^T_0 {-I_0\tau)e^{\frac{-t}{\tau} } } \, (\frac{dt}{\tau} )$

At t = 0, we set Q = 0 and obtain:

$Q = {-I_0\tau(e^{\frac{-t}{\tau} } - e^0)} \, (\frac{dt}{\tau} )\\\\Q = I_0\tau(1-e^{\frac{-t}{\tau} })$

Between t = 0 and t = τ, the charge that passes through this point is given by:

Q = I₀τ(1 - e⁻¹)

Q = 0.6321I₀τ.

Between t = 0 and t = 10τ, the charge that passes through this point is given by:

Q = I₀τ(1 - e⁻¹⁰)

Q = 0.99995I₀τ.

Between t = 0 and t = ∞, the charge that passes through this point is given by:

Q = I₀τ(1 - e⁻∞)

Q = I₀τ.

In conclusion, we can reasonably infer and logically deduce that the amount of current decreases sharply with respect to time and this makes the total charge it transports is finite.

Un tren se mueve en línea recta con velocidad media de 90 km/h. ¿que distancia recorre en el termino de de 5 horas?

jeka94

Answer:

Distance = 450 kilometres

Explanation:

Given the following data;

Speed = 90 km/h

Time = 5 hours

To find the distance covered by the train;

Mathematically, the speed of an object or body is given by the formula;

$Speed = \frac {distance}{time}$

Making distance the subject of formula, we have;

Distance = speed * time

Substituting into the formula, we have;

Distance = 90 * 5

Distance = 450 kilometres
