A larger problem would be that the threat of meteorites would be multiplied immensely (Goulding). Since there would be no resistance as the meteorite entered Earths atmosphere‚ even small meteorites would be able to penetrate our atmosphere and cause immense damage (Goulding). The damage a large meteor would cause would be catastrophic. Several ramifications that probably dont

the proton. The intrinsic angular momentum (spin) of the electron is a half-integer value in units of ħ‚ which means that it is a fermion. The antiparticle of the electron is called the positron; it is identical to the electron except that it carries electrical and other charges of the opposite sign. When an electron collides with a positron‚ both particles may be totally annihilated‚ producing gamma ray photons. The concept of an indivisible quantity of electric charge was theorized to explain the chemical

is derived and how it is used to solve problems in series and parallel connection and the resistance of a material. Ohm’s Law shows the relationship between the voltage (V)‚ current (I) and resistance (R). It can be written in three ways: V = I × R or I =V/R or R = V/I The resistance (R) of a material depends on Its length‚ cross-sectional area‚ The resistivity‚ and Resistance also depends on temperature‚ usually increasing as the temperature increases. For reasonably

Due date: March‚ 13 20144 Group Names: Hisham Sageer Objectives: Our object is to confirm Ohm’s law by analyzing the dependence of the electrical current as a function of voltage and as a function of resistance. Also‚ we studied the current flow and voltage in series and parallel. Finally‚ the lab determined the equivalence resistance of series and parallel combination of resistors and compared the results with theoretical data. Theoretical Background: The first thing that needs

experiment? Ohm’s Law - Ohm’s law states that the voltage (V) across a resistor is proportional to the current (I)‚ where the constant of proportionality is the resistance (R). Series and parallel resistors - The total resistance of resistors connected in series is the sum of their individual resistance values. The total resistance of resistors connected in parallel is the reciprocal of the sum of the reciprocals of the individual resistors. Power dissipation - where V (volts) is the

Investigation of Wireless Measure and Control Methodology for High Voltage Circuit Breaker I. INTRODUCTION The high voltage circuit breaker is the most important device for protection and control in power systems and its safety operation has always been an important requirement to be guaranteed. The working state of high voltage circuit breaker can be evaluating by the condition monitoring and fault diagnosis technology. If the data provided by the condition monitoring proved to be normal‚ the

potential difference across the two ends of a electrical conductor and between which an electric current‚ I‚ will flow. The constant‚ R‚ is called the conductor ’s resistance. Thus by the Ohm ’s Law‚ one can determine the resistance R in a DC circuit without measuring it directly provided that the remaining variable V and I is known. A resistor is a piece of electric conductor which obeys Ohm ’s Law and has been designed to have a specific value for its resistance. As an extension of the Ohm ’s Law‚

Solid state physics II Testing a Peltier Element Abstract The purpose of the experiment was to investigate the cooling properties of a Peltier element and specifically the relation between the electric current through the element and the temperature in a refrigerator cooled by the element. The “refrigerator” consisted of a cavity in a block of polystyrene foam with the Peltier element covering the opening of the cavity. A fan on top
