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.
Three similar coils, each having a resistance of 8Ω and an inductive reactance of 8Ω are connected (a) in star and (b) in delta, across a 415V, 3-phase supply. Calculate
Phase advancers: Phase advancers are used to better the power factor of induction motors. The low power factor of an induction motor is because of the fact that its stator winding
