Heating effect of electric current, Physics, ElectricityPragyan Poudyal
The document discusses the heating effect of electricity, which is one of the most common effects. It explains that when electric current passes through a conductor, the electrons collide with atoms and transfer their kinetic energy, producing heat. The amount of heat generated depends on the current, resistance of the material, and duration of current flow, as defined by Joule's law. Common applications that use this heating effect include electric irons, heaters, stoves, and light bulbs. Nichrome is often used as the heating element due to its high melting point and resistance.
Magnetic Effects Of Current Class 12 Part-2Self-employed
The document discusses various topics related to the magnetic effects of electric current:
1. It defines Lorentz force and Fleming's left hand rule for determining the direction of force on a current-carrying conductor in a magnetic field.
2. It describes the forces experienced by moving charges and current-carrying conductors in both uniform electric and magnetic fields.
3. It provides the definition of the ampere based on the forces experienced between two parallel current-carrying conductors.
Magnetic Effects Of Current Class 12 Part-1Self-employed
The document discusses the magnetic effects of electric current, including:
1) Oersted's experiment showing a current-carrying wire deflects a magnetic needle.
2) Rules for determining the direction of magnetic fields, including Ampere's swimming rule and Maxwell's corkscrew rule.
3) Biot-Savart's law, which describes the magnetic field created by a current-carrying element as proportional to the current and inversely proportional to the distance.
this presentation is based on magnetic effect of electric current, a which many of us have studies or will be studying in higher classes.this presentation is a better way of understanding the topic and in a visual way

A compass needle is placed under a copper wire carrying an electric current. When current is passed through the wire, the compass needle deflects, showing that the current produces a magnetic field that exerts a force on the compass needle. This demonstrates that electricity and magnetism are linked. The magnetic field produced by a current has concentric circular field lines around the wire. Increasing the current increases the magnetic field strength.

1) The chapter discusses control and coordination in living organisms through the nervous and hormonal systems. It describes the key parts and functions of the nervous system including neurons, synapses, reflex arcs, and the central and peripheral nervous systems.
2) The three main parts of the human brain are the forebrain, midbrain, and hindbrain. The forebrain is responsible for thinking and contains the cerebrum, hypothalamus, and thalamus.
3) Both plants and animals use electrochemical signals and hormones to coordinate responses to stimuli and control various functions. Important plant hormones include auxin, gibberellins, cytokinins, and ethylene, while important animal hormones are produced
The document discusses control and coordination in the human body. It begins by defining a neuron and describing different types of reflex actions - spinal reflexes which only involve the spinal cord and cerebral reflexes which also involve the brain. It then discusses the reflex arc and components of reflex action. Next, it describes the three main regions of the brain - forebrain, midbrain and hindbrain - and key structures and functions within each region like the cerebrum, cerebellum and brainstem. Finally, it discusses how the brain is protected by membranes, fluid and the skull, and the role of the endocrine system in releasing hormones to coordinate functions throughout the body.
The document discusses natural resource management in India. It describes renewable and non-renewable natural resources and the need to properly manage resources due to increasing population. The Ganga Action Plan aimed to reduce pollution in the Ganga River from human and industrial waste as well as religious activities. The three R's of reduce, reuse, and recycle are important for environmental conservation. Forests and wildlife are valuable natural resources and various efforts like afforestation and protected areas aim to conserve them. Traditional and community-based approaches to forest management have also shown success in conservation.
Speciation is the process by which new species develop from existing species. It occurs when populations become geographically isolated, experience genetic drift through chance changes in gene frequencies, or undergo variations through natural selection. For example, genetic drift can cause gene variants to disappear and reduce genetic variation in a population. While evolution has led to more complex body designs over time, it is not a linear process of progress but rather the production of diverse life forms shaped by their environments.
Binary fission is the mode of reproduction in amoeba, where a single parent cell divides into two equal daughter cells. This process of a parent cell splitting into two daughter cells occurs when environmental conditions are favorable, such as when there is plenty of food, water, and a suitable temperature.
