Ch.9.1 – Types of Electric Charge * Static electricity : static cling of clothes out of dryer; lightning; * Walk across carpet and touch get a shock touching metal doorknob – friction of shoes against carpet cause you acquire static electric charge * Static charge – electric charge at rest‚ stays on and eventually discharged or lost to other objects/air * Discharge – remove excess static charge so the object is neutral * Static charge last long when air is dry * Electrostatics

made from conductive filler particles combined with an elastomeric binder‚ typically silicone rubber. * QTC Material has the unique ability to smoothly change from an electrical insulator to a metal-like conductor when placed under pressure. * While in an unstressed state the QTC Material is a near-perfect insulator; with any form of deformation the material starts to conduct and with sufficient pressure metallic conductivity levels can be achieved. * QTC™ Material can be formed or moulded

1 IDENTIFICATION OF BASIC ELECTRONIC COMPONETS THEIR CHARACTERISTICS & TESTING 1.0.0 INTRODUCTION An electronic circuit is composed of various types of components. Some of these components are termed as active components because they take part in the transformation of the energy while other components‚ which only dissipate or store energy‚ are called as passive elements. The vacuum tubes‚ rectifier‚ transistors are some of-the common active while the resistances‚ which dissipate the power

Theory CONDUCTORS‚ INSULATORS AND CONDUCTIVITY Conduction of electricity in electric circuits takes place due to the presence of excess electrons in materials called conductors. Electrons move in the direction in which the potential has been applied. The ability of a conductor to conduct electricity is directly proportional to the material’s area of cross section and inversely proportional to its length. Where‚ G is conductance σ is conductivity A is area of cross section

Not only does it stop heat loss‚ but Aluminium foil is also useful for protecting objects from gaining unwanted heat. Plastic wrap insulates the heat but makes it that it is too hot to touch. Plastic wrap is reflective which should make it a good insulator‚ however the plastic is too thin and lets heat escape. the reason

Overview Of Neuron Structural and Functional Properties and Electric Circuit Parameter Models from a Cellular Perspective. Neurons serve the purpose of receiving signals coming from neighbouring neurons; they assimilate these signals‚ and generate nerve pulses. They then conduct and transmit these nerve pulses to other neurons which are capable of receiving them. Neurons are the structural constituents of the brain. Typically‚ neurons are five to six orders of magnitude slower than silicon logic
