    • 15 Pages

    Chapter 1 The History of Electric Transformer INTRODUCTION: Transformer is a device that transfers electric energy from one circuit to another‚ usually with a change in voltage. Transformers work only with a varying electric current‚ such as alternating current (AC). Transformers are important in the distribution of electric power. They raise the voltage of the electricity generated at a power plant to the high levels needed to transmit the electricity efficiently. Other transformers

    point charge q2 = 5.1 μC is located along the x-axis at a distance x2 = 9.3 cm from q1. 1) What is F12‚x‚ the value of the x-component of the force that q1 exerts on q2? -18.57 N For all of these problems we want to make use of the standard electric force equation: ̂ So for this problem with K=9*109 Nm2/C2‚ Q1=-3.5μC‚ Q2=5.1 μC‚ and r=9.3 cm we get F=-18.57 N. It’s important to realize that getting a negative force value means the charges attract. The direction of that attraction is determined

    In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electrons in the windings to flow through the external electrical circuit. It is somewhat analogous to a water pump‚ which creates a flow of water but does not create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling through a turbine or waterwheel‚ an internal combustion engine‚ a wind turbine‚ a hand crank

    I. Physical Features Electric eels are not really eels‚ they are actually ostariophysians‚ but have a strong physical resemblance to true eels. . An electric eel is mostly tail. The internal organs are compressed into the anterior (front) 1/5th of the body‚ and the rest of the fish consists of the long‚ electricity-producing tail. The tail contains the electric organs: Sachs’ organ‚ Hunter’s organ‚ and main organ. Extending down the entire tail region is an elongated anal fin. There are no dorsal
