Question: Why resistors of 330 ohm are required on I2C lines?
Answer:
The series resistors of 330 ohm added on the I2C lines is to increase the RF noise immunity.
The resistor along with the pin capacitance forms a low pass filter and filters out any high frequency signals which may get coupled to the I2C lines.
