A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.

• Transformers work on the principle of electromagnetic induction

• They have two coils, primary and secondary, which are wound around a common magnetic core

• When an alternating current flows through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil

• Transformers are used to step up or step down voltage levels i...read more

Transmission lines are used to transmit electrical power from one place to another. There are mainly two types of transmission lines.

• The two types of transmission lines are overhead transmission lines and underground transmission lines.

• Overhead transmission lines are used for long-distance transmission of high voltage power.

• Underground transmission lines are used for short-distance transmission of low voltage power.

• Overhead transmission lines are cheaper to install but requir...read more

Sling angle refers to the angle between the sling and the horizontal plane. Tension on a sling during load lifting can be calculated using trigonometry.

• Sling angle affects the tension on the sling - the greater the angle, the higher the tension.

• To calculate the tension on a sling, you can use the formula Tension = Load / (2 * sin(angle)), where 'Load' is the weight being lifted and 'angle' is the sling angle.

• It is important to consider the sling angle when determining the saf...read more

The laws of thermodynamics are fundamental principles that govern the behavior of energy and matter in the universe.

• First Law: Energy cannot be created or destroyed, only transferred or converted.

• Second Law: The entropy of a closed system will never decrease over time.

• Third Law: As temperature approaches absolute zero, the entropy of a system approaches a minimum value.

• Examples: A car engine converting fuel into motion follows the first law. A cup of hot coffee cooling down f...read more

Skin effect is the tendency of high-frequency current to flow near the surface of a conductor.

• It occurs due to the self-inductance of the conductor.

• It increases with frequency and decreases with the diameter of the conductor.

• It can cause power loss and heating in high-frequency applications.

• It is important to consider in designing high-frequency circuits and transmission lines.

• Examples include radio antennas and high-frequency power transmission lines.
