A refrigerator works on the vapor compression cycle.

• A refrigerator uses a compressor to compress refrigerant gas.

• The compressed gas then flows through a condenser where it releases heat and becomes a high-pressure liquid.

• The high-pressure liquid passes through an expansion valve, which reduces its pressure and temperature.

• The low-pressure liquid then enters the evaporator, where it absorbs heat from the surroundings and evaporates into a low-pressure gas.

• The gas is then drawn...read more

A capacitor is an electronic component that stores and releases electrical energy by accumulating and holding a charge.

• Capacitance is the measure of a capacitor's ability to store charge.

• Capacitors are commonly used in electronic circuits to smooth out voltage fluctuations, filter signals, and store energy.

• They consist of two conductive plates separated by a dielectric material.

• The capacitance value determines the amount of charge a capacitor can store.

• Capacitors can be found...read more

Potential difference is the difference in electric potential energy per unit charge between two points in an electric field.

• Potential difference is also known as voltage.

• It is measured in volts (V).

• Potential difference is the driving force that causes electric charges to flow in a circuit.

• It is the work done per unit charge in moving a charge from one point to another in an electric field.

• For example, when a battery is connected to a circuit, it creates a potential difference...read more

Longest Common Subsequence program using dynamic programming

• Create a 2D array to store the lengths of longest common subsequences

• Iterate through the strings and fill the array based on matching characters

• Trace back through the array to reconstruct the longest common subsequence
