Electric Flux: Interactive Learning
Explore the concept of electric flux through interactive simulations and animations
What is Electric Flux?
Electric flux is a measure of the number of electric field lines passing through a given area.
Just like counting water flowing through a hoop, we can count electric field lines passing through a surface!
Remember: Electric flux (Φ) depends on:
- The strength of the electric field (E)
- The area of the surface (ΔS)
- The angle (θ) between the field and the surface normal
The mathematical formula for electric flux is:
Φ = E·ΔS = E ΔS cos θ
0°90°
Tilt the surface to see how the flux changes!
Everyday Example
Think of standing in a light rain with an umbrella. The amount of rain hitting your umbrella depends on:
- How heavy the rain is (like the strength of the electric field)
- The size of your umbrella (like the area)
- How you tilt your umbrella (like the angle θ)
