Physics

Principle objective of this lecture is to present on Electricity Practical. It is tutorial study based presentation. here briefly describe on Charges; Electrons; Voltage; Current; Series; Parallel and Resistance. There are kinds of electrical…

Major objective of this lecture is to present on What is a Motor? Motor is a device that changes electrical energy to mechanical energy that can do…

The aim of this lecture is to present on What is a Generator? Generator is a machine that changes mechanical energy to electrical energy. Usually use moving magnets…

Prime objective of this lecture is to present on What is an Electromagnet? Electromagnet is a magnet made from a current bearing coil of wire wrapped around…

Resistance is the opposition to the flow of an electric current, producing heat. The greater the resistance, the less current gets through. Good conductors have low resistance. Measured…

Basic objective of this lecture is to present on How can we Control Currents? We can control currents with circuits. Circuit is a path for the…

General objective of this lecture is to present on Electricity and Magnetism. Electromagnetism is a branch of physical science that describes the interactions of electricity and magnetism,…

Main objective of this lecture is to present on How to Measure Precipitation. Raingage – A cylindrical container that collects rainfall and measures its depth. Tipping-bucket gage –…

Snow falls from clouds that contain enough cloud droplets and ice crystals for precipitation to form. In order for snow to reach the ground without melting,…

When rain clouds are pushed up into cold air the rain drops form and become heavy enough to be pulled to the ground by gravity. Water…

Major objective of this lecture is to present on Rainfall Measurement. Most rain gauges generally measure the precipitation in millimetres equivalent to litres per square metre. In this…

Several types of precipitation exist and depend on the atmospheric temperature profile: Snow; Rain; Graupel and hail; Sleet and Freezing rain. Snow occurs from the Bergeron process, riming, and aggregation. The nature…
