The least count of a micrometer is the smallest measurement that can be accurately read on the micrometer scale.

• The least count is determined by the number of divisions on the micrometer scale and the pitch of the screw

• It is calculated by dividing the pitch of the screw by the number of divisions on the scale

• For example, if the pitch is 0.5 mm and there are 100 divisions on the scale, the least count would be 0.005 mm

Semiconductor is a material that has electrical conductivity between that of a conductor and an insulator.

• Semiconductors are used in electronic devices such as transistors, diodes, and integrated circuits.

• They are made of materials such as silicon, germanium, and gallium arsenide.

• The conductivity of semiconductors can be controlled by adding impurities through a process called doping.

• Semiconductors are essential compon...read more
