Parameters of transmission line include resistance, inductance, capacitance, and conductance.
Resistance: opposition to the flow of current
Inductance: ability to store energy in a magnetic field
Capacitance: ability to store energy in an electric field
Conductance: ability to conduct electric current
Examples: coaxial cable, waveguide, twisted pair cable
Hysteresis curve is a graphical representation of the relationship between magnetic field strength and magnetization of a material.
It shows the lag between the magnetic field and the magnetization of a material.
It is used to study the magnetic properties of materials.
It is commonly used in the design of magnetic circuits and devices.
Examples include transformer cores, magnetic storage devices, and electric motors.

We use step-up transformers to reduce power loss during transmission by increasing voltage and decreasing current.
Step-up transformers increase voltage and decrease current, which reduces power loss during transmission.
This is because power loss is proportional to the square of the current, so reducing current reduces power loss.
For example, power is transmitted over long distances at high voltages (e.g. 500 kV) to red...
Power factor is the ratio of real power to apparent power in an AC circuit.
Power factor is a measure of how efficiently electrical power is being used.
It ranges from 0 to 1, with 1 being the most efficient.
A low power factor can result in higher energy costs and equipment damage.
Capacitors can be used to improve power factor.
Power factor is important in industries where large amounts of electrical power are used.

Different types of LCs include commercial, standby, revolving, transferable, and back-to-back LCs.
Commercial LCs are used for regular trade transactions.
Standby LCs act as a guarantee of payment in case of default.
Revolving LCs are used for multiple shipments over a period of time.
Transferable LCs allow the beneficiary to transfer the credit to another party.
Back-to-back LCs involve two separate LCs, one for the buyer

Electroplating is a process of depositing a layer of metal onto a surface using an electric current.
Electroplating involves immersing the object to be plated (called the substrate) into a solution containing metal ions.
A direct current is then passed through the solution, causing the metal ions to be attracted to the substrate and form a metal coating.
Common applications of electroplating include improving the appearan...
