Voltage is the difference in electric potential between two points in a circuit, measured in volts.

• 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 energy available to move electrons

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

Handling pressure during work load requires effective time management, prioritization, delegation, and stress management techniques.

• Create a to-do list and prioritize tasks based on urgency and importance

• Delegate tasks to team members if possible

• Take breaks and practice stress management techniques such as deep breathing or meditation

• Communicate with colleagues and managers about workload and seek support if needed

• Maintain a positive attitude and focus on solutions rather tha...read more

The combustion chamber is where fuel and air are mixed and burned in an internal combustion engine.

• It is a part of an internal combustion engine where the fuel-air mixture is ignited and burned.

• The combustion chamber is designed to contain and control the combustion process.

• It is typically located within the cylinder head of an engine.

• The shape and design of the combustion chamber can affect engine performance and efficiency.

Communication protocols are a set of rules that govern the exchange of data between electronic devices.

• Protocols ensure that devices can communicate with each other effectively and efficiently.

• Examples of communication protocols include Bluetooth, Wi-Fi, and Ethernet.

• Protocols can be either wired or wireless, and can be used for different purposes such as data transfer, device control, and synchronization.

• Some protocols are standardized, while others are proprietary and speci...read more

ADAS stands for Advanced Driver Assistance Systems, which are safety features designed to assist drivers in the driving process.

• ADAS features use sensors and cameras to monitor the vehicle's surroundings and provide warnings or assistance to the driver.

• Examples of ADAS features include adaptive cruise control, lane departure warning, automatic emergency braking, and blind spot detection.

• These features help improve safety, reduce accidents, and enhance the overall driving expe...read more

Python code to write Fibonacci series

• Use a loop to generate the series

• Start with 0 and 1 as the first two numbers

• Add the previous two numbers to get the next number

Python code to print an Armstrong number

• An Armstrong number is a number that is equal to the sum of its own digits raised to the power of the number of digits

• Loop through the range of numbers and check if each number is an Armstrong number

• Use the len() function to get the number of digits in a number

• Use the pow() function to raise a number to a power

• Use the sum() function to get the sum of a list of numbers

Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.

• Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• It is named after the German physicist Georg Simon Ohm who first formulated it in 1827.

Refrigerant system is a closed loop system that absorbs heat from a low-temperature area and releases it in a high-temperature area.

• Refrigerant circulates through the system to absorb and release heat

• Compressor increases the pressure of the refrigerant gas

• Condenser cools the refrigerant gas into a liquid

• Expansion valve reduces the pressure of the liquid refrigerant

• Evaporator absorbs heat from the surrounding area to cool it down

• Common refrigerants include R-134a, R-410A, and ...read more

Rotate a list by 2 indices

• Create a new list and add elements from the original list starting from index 2 to the end

• Add elements from the original list starting from index 0 to 1 at the end of the new list

• Alternatively, swap the first 2 elements with the last 2 elements, then rotate the remaining elements

Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance allows a child class to override a method from its parent class, providing different functionality.

I chose Java for its platform independence, strong community support, and extensive libraries.
