Understanding Electric Fields

If I told you the space around you is full of invisible arrows that push charges around—even

when nothing is touching—would you believe me? Welcome to the world of electric fields.

Electric fields describe how a charge affects the space around it. If you place a tiny

positive test charge anywhere in that space, the electric field tells you which

direction it will be pushed and how strongly. Here’s the key idea: - Positive charges

are sources of electric fields. Field lines point outward from them. - Negative charges

are sinks of electric fields. Field lines point inward toward them. These field lines

aren’t physical objects—they’re just a visual tool to help show how forces act in space.
