Lead:
Atomic number
82
Symbol
Pb
Atomic weight
207.2
Discovery
Known since prehistoric time
Electronic configuration
6p2
Properties:
1. It is a heavy, soft and malleable metal with blue gray colour.
2. It shows a metallic luster when freshly cut but it gets oxidized soon.
3. It can be easily rolled into sheets and pipes or can be extruded to form pipes but cannot be cut into fine wires.
4. It is corrosion resistant.
Uses: Lead is used of the manufacturing of plates of storage batteries. It is used in covering electric cables. It is used as lead accumulators. Tin lead-alloy is used for soldering wires.
What is the difference among a fiber optics manufacture and a fiber optics system manufacture? It is a question that would sound silly in other industries although not in this
Core type Transformers: in this type of transformer the windings enclose the core (fig .given below). Both the windings are separated and half of every winding is placed on ever
A metal has a work function of 4.80 eV. Will ultraviolet radiation with a wave length of 385 nm be able to eject a photoelectron from the metal?
Do fiber optic transmits the radiation? Light is a radiation; hence, the answer is yes. Several fibers, depending upon the nature of the materials from that they are made, tran
Electrostatic Induction: Electrostatic Induction is the process in which a charged object charges another neutral object without touching it.
It is a highly doped p-n junction which is not smashed by high reverse current. The breakdown voltage is made very sharp. In the forward bias, the zener diode do as ordinary diode.
Step to improve Power Factor By using static capacitor: Static capacitor is generally used to get better the power factor of the power system. As the capacitor draws leadi
