Types of Gears
There are many types of gears. Gear is generally defined as the rotating circular machine part which is having the teeth cut on its surface and these teeth mesh with the other teeth to transmit the torque and speed. Gear devices can generally change the torque, speed, and direction of a power source. Two or […]
Micrometer (Screw Gauge): Working Principle, Least Count, Parts and Units
The micrometer is also known as the micrometer screw gauge and is used to measure the dimensions particularly linear dimensions of the objects. It is used to measure the outside diameter, thickness, and length of solid objects. Parts of the Micrometer First of all, we will check the parts of the micrometer and will understand […]
Vernier Caliper: Diagram, Least Count, Formula
Vernier Caliper is a measuring instrument that is used to take the dimensions of objects whether the dimension is linear or measuring the diameter of round objects. Vernier Caliper is invented by French mathematician Pierre Vernier in 1631. The main use of the vernier caliper over the main scale is to get precise and accurate measurements. […]
Ohm’s Law- Definition, Formula, Examples
Ohm’s law is a formula that states the relationship between Voltage ‘V’, Current ‘I’, and Resistance ‘R’ in an electric circuit. It is one of the important and most basic laws of electrical circuits. Before proceeding further in detail with Ohm’s Law, we ought to understand the three important terms that are Voltage, Current, and […]
