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 … Read more

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 … Read more

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 … Read more

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 … Read more

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 … Read more

Static electricity is an excess of electric charge trapped on the surface of an object. The charge remains until it is allowed to escape to an object with a weaker or opposite electrical charge, such as the ground, by means of an electric current or electrical discharge. Static electricity is named in contrast with current … Read more
