F.left hand theorem states that the magnetic field around a current-carrying conductor can be determined using the left hand rule.

• States that if the thumb, forefinger, and middle finger of the left hand are extended at right angles to each other, with the forefinger pointing in the direction of the current, the thumb in the direction of the magnetic field, then the middle finger points in the direction of the force exp...read more

Hydraulics is a branch of engineering that focuses on the mechanical properties of liquids.

• Hydraulics deals with the transmission of force through the use of liquids.

• It involves the study of fluid dynamics and how fluids behave under pressure.

• Hydraulic systems are commonly used in various applications such as heavy machinery, aircraft control systems, and automotive brakes.

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core made of iron or other magnetic materials.

• Step-up transformers increase voltage levels, while step-down tr...read more

Tan Delta testing is a diagnostic test used to measure the insulation quality of electrical equipment.

• Tan Delta testing measures the power factor of insulation materials to detect any defects or deterioration.

• It helps in identifying potential issues before they lead to equipment failure or breakdown.

• The test involves applying a voltage to the insulation and measuring the current flowing through it.

• Results are compared ...read more
