Transformer
The transformer in the simplest way can be described as a thing that steps up or steps down voltage. In a step-up transformer, the output voltage is increased and in a step-down transformer, the output voltage is decreased. The step-up transformer will decrease the output current and the step-down transformer will increase the output current…

Types of Gears
We can have various types of gears depending upon their axe’s position and can be classified into intersecting, non- intersecting shafts and parallel shafts. Some types of gears are listed below: Internal gear Mitre gear Worm gear Screw gear Spiral bevel gear Bevel gear Gear rack Spur gear Helical gear Internal gear These type of…

Difference Between Mirror and Lens
Even though both these devices are used in optics but there is a difference between mirror and lens. The mirror is a device is based on the principle of reflection whereas the lens is based on the principle of refraction. Both these devices are used in various industries such as photography or astronomy etc. Difference…

Difference Between Scalar and Vector
Usually, both these terms sound the same, but there is a difference between scalar and vector quantities. Both these quantities are used to represent the motion of an object. Difference Between Scalar and Vector A scalar quantity is different from a vector quantity in terms of direction. Scalars don’t have direction whereas vector has. Due…

Difference Between Work and Power
Work is defined as the process of energy transfer to the motion of an object through the application of force. This is usually represented as the product of force and displacement. The SI unit of work is Joule. Power is defined as the amount of energy transferred in unit time. The SI unit of power…

Difference Between KVA and KW
There is a noticeable difference between KVA and KW even though both are used to represent electric current. These units are power ratings used in every measuring instrument for measuring the current characteristics. Both the units are used to express power and are abbreviations of kilovolt amperes and kilowatts. In this session, let us know…

Difference Between Gravitation and Gravity
The terms Gravitation and Gravity define the phenomenon that causes masses to attract each other. These terms are used interchangeably, and it is permitted to do so. However, in some fields of study, the difference between gravitation and gravity is more prominent. The term ‘Gravity’ is used when the gravitational field is taken as a…

Difference Between Heat and Temperature
We often talk about heat and temperature in our daily life in terms of weather or sometimes in terms of temperature. But do we know the difference between heat and temperature? It is important to realize the minute difference between heat and temperature scales of measuring the hotness or coldness of any object. Heat vs…

Difference Between Resistance and Resistivity
Resistance is defined as the property of the conductor which opposes the flow of electric current. It is also defined as the ratio of the voltage applied to the electric current flowing through it. The resistance of a conductor depends on the length, area of cross-section, and the nature of the material that is used…

Difference Between Mass and Weight
The difference between mass and weight is one of the most frequently asked questions. Some students often use the terms mass and weight interchangeably, which is completely wrong. There are several differences between mass and weight that are discussed here in detail. Before going to the mass and weight difference, it is important to know…
