Variables: Independent variable: one metal use in one voltaic half cell: (half of the redox reaction occurs at each half cell‚ Therefore‚ we can say that in each half cell a half reaction is taking place ‚ when the two halves are connect together with a wire and a salt bridge‚ and electrochemical cell is created ) Dependent variable: Voltage Controlling variables: Volume of solution; a higher volume on one side of the cell of the cell would provide more electrons‚ increasing the potential energy‚

process” What is MIG welding? MIG welding which stands for Metal Inert Gas‚ also known as Gas Metal Arc Welding (GMAW) is a welding process in which an electric arc forms between the wire electrode and the metal work piece. This then heats the metal work piece as well‚ causing them to melt and join together. Along with the wire electrode a protective gas called shielding gas is fed through the welding gun which shields the whole process of the weld from contaminants in the air. This process can be semi-automatic

Calder transported his little theater in suitcases and performed it for his friends. During his performances‚ Calder invented ways to simulate the flight of birds: "These are little bits of white paper‚ with a hole and slight weight on each one‚ which flutter down several variously coiled thin steel wires which I jiggle so that they flutter down like doves " (Alexander

determine the resistivity of a conducting wire given two known resistors. The main property of resistivity is that it represents how easily electrons can flow through a material. A Galvanometer is used to measure the current of the circuit and the Wheatstone Bridge is used to measure the resistances and determine the unknown resistance. This experiment also relates Ohm’s Law to determine the resistivity using the resistance of the wire‚ length of the wire‚ and cross sectional area. In order to

SWITCHING • The simplest switching structure is a rectangular array of crosspoints as shown in Figure 5.2. • This switching matrix can be used to connect any one of N inlets to any one of M outlets. • If the inlets and outlets are connected to two-wire circuits‚ only one cross-point per connection is required. • Rectangular cross-point arrays are designed to provide intergroup (transit) connections only‚ that is‚ from an inlet group to an outlet group. • Applications for this type of an operation

Diodes Diodes are components that allow current to flow in only one direction. They have a positive side (leg) and a negative side. When the voltage on the positive leg is higher than on the negative leg then current flows through the diode (the resistance is very low). When the voltage is lower on the positive leg than on the negative leg then the current does not flow (the resistance is very high). The negative leg of a diode is the one with the line closest to it. It is called the cathode. The

Before you begin‚ form a hypothesis that reflects which gauge of wire‚ materials‚ voltage‚ and number of winds you think will produce the strongest electromagnet. (HINT: Use the following list to help fill in the blanks below.) If I use Large gauge of wire and Copper as the material‚ with a voltage of 100 Volts and 100 number of winds‚ then this will produce the strongest electromagnet. Gauge Choices: Large

Difference ? original X 100 This shows that the results were good‚ as 8% is a very small margin of error. The error bars on the graph show that the most inaccurate result was the 60cm result. This could be down to an error in the measurement of the wire or a temperature rise. The two results for 100cm are exactly the same‚ and it is near to the manufacture’s line‚ so this is the most accurate point. The other three readings have almost the same inaccuracy‚ an average of
