gasoline to the engine. But it also has a set of batteries that supplies power to an electric motor. Both the engine and the electric motor can turn the transmission at the same time, and the transmission then turns the wheels. In a parallel hybrid, both the electric motor and the gas engine can provide propulsion power. The other type is a series hybrid. In the series hybrid the gasoline engine turns a generator, and the generator can either charge the batteries or power an Hybrid Vehicles 3 electric

between two large, closely spaced plates, von Kleist found the energy density could be increased dramatically compared with the situation with no insulator. Daniel Gralath improved the design and was also the first to combine several jars to form a battery strong enough to kill birds and small animals upon discharge 1767: Joseph Priestley proposes an electrical inverse-square law. 1774: Georges-Louis LeSage builds an electrostatic telegraph system with 26 insulated wires conducting Leyden-jar charges

read anytime to get an information needed. • iBMI (invasive brain machine interface) : it’s a type of device that goes in the patient’s brain to get data from it and send to a prosthesis to get movement that is needed. One real problem is how much battery the equipment is going to use to work. With this I found a good explanation about the problem at Wikipedia’s definition about Neuroprothetics: • Class-E power amplifiers, and we will present three transmission standards which are used in transcutaneous

power transmission system see a considerably high power loss that in 26-30% in developed countries and about30-40% in developing or underdeveloped countries. The primary reason for the losses during transmission and distribution of power is the resistance of the wire used for grid. Therefore, inefficiency in power transmission along with ever increasing need of electricity as a basic necessity calls for an efficacious and efficient transmission method. Since, wireless power transmission system provides

matter that involves our contemporary life style. According to physicist Boyle, scientific description of ‘energy’ is the ability to accomplish tasks which also defined as an individual’s capability to transport an object involving some sort of resistance. This paper talks about common energy usage in our homes everyday lives as well as the resources that the energy is derived from. Renewable and non-renewable energy is also discussed evaluating the impact on the humans and the environment result

Applications The “wonder material”, known as grapheme holds many superlative qualities allowing for it to be integrated into a huge number of applications. At the start, grapheme will be used to help improve the performance and efficiency of current materials and substances, but soon after it will be developed in conjunction with other two-dimensional crystals to create more amazing compounds to suit a wider range of applications. The following are a few science fields where grapheme may be used

capacitive reactance. For example, Z = 8 + j 6Ω means that a resistor of 8Ω is in series with an inductive reactance of 6Ω. Polar Notation: Z = M ∠θ, where M is the magnitude of the reactance and θ is the direction with respect to the horizontal (pure resistance) axis. For example, a resistor of 4Ω in series with a capacitor with a reactance of 3Ω would be expressed as 5 ∠-36.9° Ω. In the descriptions above, impedance is used as an example. Rectangular and Polar Notation can also be used to express amperage
