Magnetic Effect of Electric Current and Magnetism

Magnetic Effect of Electric Current and Magnetism. Magnetic flow of current action: The flow of electricity through a conductive wire creates a magnetic field around the wire. Power flows to the magnetic action of the incident. Right hand rule: No flow of current flowing through a conductor. The other direction is indicated by the right…

Electromagnetic Induction & Alternating Current

Electromagnetic Induction & Alternating Current. Electromagnetic induction: A dynamic magnet or taritbahi circuit electromotive force and electric current passing through a closed circuit of the process to generate the flow of electromagnetic induction. When passed through a closed coil magnetic or magnetic balarekhara balarekhara total number of changes, then a short-term electromotive force of the coil…

Introduction to Modern Physics

Introduction to Modern Physics Introduction to Modern Physics. The term recent physics refers to the post-Newtonian beginning of physics. Put purely, modern physics agreements with the fundamental construction of the tiniest particles in nature ("quantum" mechanics), as well as a laborious sympathetic of the important communication of atoms, unspoken as forces. Small speeds and large…

Physical Optics

Physical Optics Physical Optics. In physics, physical optics, or movement optics, is the division of optics which educations interfering, deflection, polarity, and other miracles for which the beam estimate of symmetrical optics is not valid. This usage inclines not to contain special effects such as substantial sound in visual communiqué, which is considered in the…

Geometrical Optics

Geometrical Optics. Light. is a form of radiant energy or external cause which creates sensation of light when enters into our eyes. This radiant energy travels from one place to another place in the form of transverse waves. Ligh tpropagates in a straight line in homogeneous medium. But when light is incident on a secondmedium…

Semiconductor and Electronics

Present ear is called the era of Electronics. Now-a-days application of electronics are seen in our everyday life-like radio, television, VCR, computer, interne, mobile, i-pad etc. Electronics is originated from the word electron. Electronics in a branch of physics dealing with the flow of electrons in devices like valves or semi-conductor devices. The working of…

New Curriculum Physics Note of Current Electricity

Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by…
