Magnetic Field Large Amount
1,319 wordsA transformer is a device that raises or lowers voltage and is used mostly with alternating current, or ac. A transformer has no moving parts, is simple, rugged, durable, and can be up to ninety-nine percent efficient. Cities use a large amount of power, and power is based on the amount of current in electricity. A transformer works by changing the amount of voltage and current of electricity. When voltage is increased current in electricity is decreased or if voltage is decreased current in ele...

Cross Sectional R R
864 wordsDetermination of r for a Metallic Conductor To determine the resistivity (r) of a given sample of wire Physical factors that affect the resistance of a conductor are length, cross sectional area and a constant that depends upon the material called the resistivity. The resistance per unit length is the same all along a uniform wire so if the resistance of different lengths of a wire is found out, the resistivity can be calculated. Resistance of a material, R = Voltage / Current Resistance of a co...

8 And 10 Ohms 127 5 135 Voltage
462 wordsPurpose: The purpose of this lab is to see if and how Ohms Law applies in a circuit that doesnt have a resistor. Theory: Equations Resistance = Voltage/Current R = V/I Voltage = Current Resistance V = I R Current = Voltage/Resistance I = V/R Hypothesis: I hypothesize that the resistance will be between 8 and 10 ohms. Procedures: Assemble a circuit with a multimeter, to measure the current, a voltmeter, to measure the volts, and a resistor that will provide the resistance. Next, a hand-held gener...

Mccabe Thiele Graphical Hetp Vs Vapor Velocity Column
5,222 wordsThis report Chemistry: Destination Abstract This report outlines the steps taken to separate a 50: 50 by volume ethanol and isopropanol side stream. The resulting separation must contain no more than 3 % alcohol impurity in each product. A laboratory column, run at total reflux, was utilized to scale up to a forty foot high by one foot diameter column. The laboratory column allowed the team to determine vapor velocities and HETP values for the 0. 24 inch Pro-Pakq packing. HETP is defined as the ...

1,768 wordsThe objective Don John Purpose The objective of this lab is to introduce the Bipolar Junction Transistor (BJT). A BJT is a three terminal device composed of an emitter, base, and collector terminals. In this lab we will introduce two major types of BJT? s: npn and pnp. The first, npn, has an n-type emitter, a p-type base and a n-type collector. On the other hand the pnp has a p-type emitter, a n-type base, and a p-type collector. Also the transistor consists of two major pn junctions, the emitte...

Speed Of Light Lightning Bolt
3,469 wordsElectricity Electricity WHAT IS ELECTRICITY Electricity is a form of energy. Thats because we can use electricity to do things for us, like run machines and computers. Electricity also can be transformed into other types of energy such as heat or light and is used to heat our homes, light our cities and towns and power the computers we are using. Electricity is the type of energy that is invisible. Its made of moving electrons that are so small and move so fast that we cannot see them. The elect...

Magnetic Field Generate Electricity
2,438 wordsPlanning Aim and hypotheses According to Flemings Rule, electricity is generated when movement occurs in the magnetic field. Alternatively, switching direction of the magnetic field also works. Alternating current is a good way of alternating the field direction. The electricity generated, of in the other words, the electromotive force, is measured in volts. By varying different parts of the apparatus, the EMF output could also vary. The aim of this investigation is to establish a connection bet...

1,679 wordsPlanning Aim To find the factors that affect the amount of E. M. F. being produced. The amount of E. M. F. produced during the experiment when each type of factors is change. Background knowledge Electro-motive-force is the energy being supply to a charge. Battery is a type of energy. The energy that it provides is voltage. Battery voltage is sometime called electro-motive-force because it is used to pump around the electrons in the wire. The force can be generates by the moving of magnetic fiel...
