This video explains what a resistor is using a simple visual idea.
From the outside, a resistor looks ordinary.
Inside, it contains a long, thin, coiled path that makes the movement of electrons more difficult.
A resistor does not stop electric current.
It limits it.
That limitation happens because the path inside is:
long,
narrow,
and full of friction.
Understanding this simple idea helps explain how circuits behave, even before using formulas or measurements.
Personal learning challenge
Look at the image carefully.
Compare a resistor with a normal wire.
Ask yourself what changes when the path becomes longer and narrower.
Understanding begins when you look closely.
