potential difference supplied to the circuit is 2V. Resistors in series and in parallel Resistors in Series When resistors are in series with each other there total resistance is just there individual resistance added together. Resistors in parallel When resistors are in parallel with each other there total resistance is found using the equation below. Current in series and parallel circuits Conservation of charge – ” the total charge flowing into a junction of wires must equal

ascertained of a metal wire and thus find the resistance of the wire by deriving the inverse of the gradient of the graph. Skill: Planning & Designing Theory: Resistance is a property of any object or substance to resist or oppose the flow of an electrical current. The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. This is according to Ohm’s law. The unit of resistance is the Ohm which has the Greek letter

surviving the many hardships they were presented with. In “The Diary of Anne Frank” and “Resistance During the Holocaust”‚ it explains how individuals would use different methods to passively resist. As a response to conflict‚ people passively resisted by maintaining hope‚ preserving culture‚ and providing safety. Many Jews in ghettos and death camps would passively resist by maintaining

often uses genes for antibiotic resistance..." Most genetically engineered plant foods have this antibiotic resistance gene. The gene in these plants primarily have two negative effects. Eating these plants/foods that have this gene will lower the effectiveness of antibotics to fight disease when you are taking antibiotics with meals. "Antibiotic-resistance genes produce enzymes that can degrade antibiotics." For example‚ if you eat a potato with a antibiotic resistance gene at the same time you are

the World Methicillian-resistant Staphylococcus aureus‚ also known as MRSA‚ is any strain of the bacteria S.aureus that has evolved a resistance to beta-lactam antibiotics‚ which includes the penicillin and cephalosporin family. This creates world-wide concern because there aren’t too many antibiotics left to treat S. aureus if the drug evolves greater resistances to stronger antibiotics. MRSA is one of the top leading causes of nosocomial acquired infections. According to an article featured

There were many resistances from slaves‚ violent and non-violent‚ during the period of slavery in the BWI. Violent resistance was in the form of revolts and rebellions and non-violent resistance included actions such as suicide‚ poisoning‚ avoiding work and maroonage. However‚ there were three violent resistances which stood out. These three were Bussa Rebellion in Barbados (Easter 1816)‚ Demerara Revolt in Guyana (August 1823) and the Sam Sharp Rebellion in Jamaica (December 1831). These rebellious

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

equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same. In accordance with the law‚ is resistance decreased and voltage stayed the same the current would increase. The increase is inversely proportional to the resistance. 4. Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same. Resistance is the opposition to current flow. In a light bulb if the r stayed the
