When someone is trying to draw and giving some pressure on the surface, then the circuit reads the pressure and sends the signal through the stylus. There is one more thing and that is a pressure-sensitive capacitor. It measures the accurate line and length following the signal.

There is one more signal worked called Electromagnetic signal. This signal received from the circuit of the stylus. In the short term, we can say that the stylus is actually working as an antenna that sends the signal to the tablet.
