PHYSICS II ELECTRICITY‚ MAGNETISM‚ SOUND‚ AND LIGHT SERIES CIRCUIT In this unit you’ll begin learning how to analyze circuits. Circuit analysis means looking at a schematic diagram for a circuit and computing the voltage‚ current‚ or power for any component in that circuit. Closely related to the task of circuit analysis is the task of troubleshooting‚ which means figuring out what is wrong in a circuit that is not working correctly. Analyzing and troubleshooting go hand in hand; when a circuit

Coursework - Resistance of a Wire Coursework Introduction (Theory) In this piece of Coursework I am going to investigate the resistance in a piece of wire. Resistance is the force that slows down the flow of electrons; this can be due to electrons colliding. The total length of the wires will affect the amount of resistance. The longer the wire‚ the more resistance that there will be. This is also true for thickness of wire; the thinner the wire is the more resistance. Resistance is measured

SENIOR SECONDARY EXAMINATION Scheme of Physics Practical Examination Duration: 3 hours Maximum Marks: 20 There will be a practical examination of 20 marks apart from the theory examination. The distribution of 20 marks is as follows: (i) (ii) (iii) Viva Record Book Two Experiments 4 Marks 2 Marks 14 Marks Note: There are 30 experiments in three Groups A‚ B and C. In the practical; examination candidates has To do two experiments which should not be from the same group and each experiment carries

Procedure Part I Wire Resistance: As wire length (cm) increases‚ the resistance (Ω) increases As wire area (cm2) increases‚ the resistance (Ω) decreases As wire resistivity (Ωcm) increases‚ the resistance (Ω) increases Procedure Part II: Ohm’s Law: Electricity‚ Magnets‚ and Circuits Ohm’s Law mA is milliamps‚ and 1000 milliamps equals one Ampere. Move the potential (volts) and resistance (ohms) sliders and observe the current (amps) As voltage increases‚ current increases. As resistance increases‚ current

Strings of holiday lights can be designed in one of two ways. In some strings of lights‚ each light is connected to the others along a single wire (in series). In others‚ each light is attached to its own wire (in parallel). Suppose a single light bulb burns out. How do you think

experiment is to test the predictions for current‚ voltage and resistance of the relationships of parallel and series circuits. The procedures strive to prove that the theoretical outcomes are consistent with the corresponding measured results. After setting up the closed circuits we want to test our own results into the equations and conclude if they are true. In the same circuit‚ there are specific equations that show how current‚ resistance and voltage behave. The equations or predictions differ

Mechanisms of Silver Nanoparticle Action in Bacteria and Potential for Bacterial Resistance The antimicrobial activity of silver in general‚ and of silver nanoparticles in particular‚ is of significant interest because it appears to be independent of the strain of bacteria. Crucially‚ antibiotic resistant strains‚ MRSA (methicillin‚ or multiple-resistant Staphylococcus aureus)‚ E. coli O157‚ and others are affected by silver [6]. The reasons for this are not fully clear as yet‚ but could be related
