Name: Sukhdev Singh Shah Form: 10GK Introduction: Resistance: Electrons move more easily through some conductors when a potential difference is applied. Resistance is determined by how good or bad a conductor a material is. A good conductor has a low resistance while a poor conductor has a high resistance. OHM ? Resistance is defined by: R= V/I If I= 2A when V= 12v, then R= 12/2 = 6 ? Resistors: Some conductors are made from carbon or alloy wires, and are intended to have resistance, so we call them resistors. Resistors used in everyday life have values ranging form usually a few ohms, but go up to millions of ohms. Resistors in a series: The resistors below are in Series. The current flowing through all (I) is the same, and the separate potential difference across then is the same as the total potential difference across the 3 (V). i.e. V= V1 + V2 + V3 If R is the combined resistance, V= IR Resistors...
