In physics: “a specific field exerting a pressure at the point fees is referred to as the electrical discipline”
let us clear up an instance here to make your concept extra deep and actual.
Example:
How to calculate the magnitude of an electric field when a charge of \(5 \times 10^{-6}\) C exerts it at a distance of 2 m?
Solution:
Using the electric field strength equation:
\[ E = \frac{k \cdot Q}{r^2} \]
Substitute the given values:
\[ E = \frac{8.98 \times 10^9 \cdot 5 \times 10^{-6}}{(2)^2} \]
\[ E = \frac{8.98 \cdot 5 \cdot 10^9 \cdot 10^{-6}}{4} \]
\[ E = \frac{44.9 \cdot 10^9 \cdot 10^{-6}}{4} \]
\[ E = \frac{44.9 \cdot 10^{9-6}}{4} \]
\[ E = \frac{44.9 \cdot 10^3}{4} \]
\[ E = 11.225 \cdot 10^3 \, NC^{-1} \]
\[ E = 1.1225 \cdot 10^4 \, NC^{-1} \]
You can verify the result using an electric field strength calculator. Calculating the electric field helps manage safe distances from electrical sources and determine the impact of high electric field areas in your environment.
The electrical subject is constantly gift within the surroundings of the charged body and exerts a pressure on the neighbouring charges as nicely. whereas, the electric force depends on the electric field and does now not exist within the absence of the electrical pressure.
while the electrical subject is produced through a stationary charge, then it's miles referred to as the electrostatic subject.
In a charged conductor, the expenses stay on the surface of it and there exists a sturdy loss of expenses internal it. this is why the electrical subject of the charged conductor is usually zero that might be effortlessly checked the use of a loose on line electric powered subject calculator. for instance, you could degree this area by means of setting parameters in electric area equation.
while two electric area lines intersect each other, tangents are drawn there. It suggests different guidelines of the electrical field strains which is not possible. this is why electric field strains can by no means intersect each other.
