The continuous flow of electrons is called a current. An example is a battery making a light turn on using a wire.
Resistance is the difficulty an electric current faces to pass through an object.
Ex: A wire bending in a zig-zag pattern.
The close loop that current flows through.
Ex: A lamp plugged up into a wall.
