Q1. What is I2C
Ans. 
I2C (Inter-Integrated Circuit) is a multi-master, multi-slave, packet-switched, single-ended, serial communication bus.
• I2C uses two wires: SDA (Serial Data Line) and SCL (Serial Clock Line).

• It supports multiple devices on the same bus, allowing for easy communication.

• Commonly used in sensors, EEPROMs, and RTCs (Real-Time Clocks).

• I2C operates at standard speeds of 100 kHz and 400 kHz, with high-speed modes up to 3.4 MHz...read more

• Voltage is the force that pushes electric current through a circuit

• It is measured in volts (V)

• Voltage is the potential difference between two points in a circuit

• Higher voltage means more potential energy available to move electrons

• Voltage can be DC (direct current) or AC (alternating current)

Q2. What is insulator
Ans. 
An insulator is a material that does not conduct electricity, heat, or sound.
• Insulators prevent the flow of electricity, heat, or sound.

• Common insulating materials include rubber, glass, plastic, and ceramic.

• Insulators are used to protect against electric shocks, prevent heat loss, and reduce noise transmission.

• Insulators have high resistance to the flow of electrons.
