Crystallography
Subject and UNIT: Physics for Electronics Engineering: Unit I: Crystallography
A crystal is an array of atoms in three dimensions. As a matter of convenience, these atoms can be associated with a set of imaginary points in space.

Materials differ from one another in their properties. Some solids are brittle, some are ductile, some are malleable, some are strong, some are weak, some are good conductors of heat and electricity, some are bad-conductors of heat and electricity, some are magnetic, some are non-magnetic and so on.

Circuit breakers are electrical devices that offer protection against fault current. They use different medium to safely extinguish the arc such as air, oil, SF6 or vacuum etc. MCCB or Molded Case Circuit Breaker uses air as the dielectric medium to break a circuit.

All fuses need to be replaced with MCB "Miniature Circuit Breaker" for better safety and control when they have done their job in the past. Unlike a fuse, an MCB operates as an automatic switch that opens in the event of excessive current flowing through the circuit and once the circuit returns to normal, it can be reclosed without any manual replacement.
