  • Series and parallel circuit problem solving

    Introduction My research is based on how Ohm’s law 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...

    complete circuit. A complete circuit requires a battery, wires and a light bulb. 2. Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different. Both series and parallel circuits must have all the components of a complete circuit in order to work. These two circuits differ in the way the electrons are able to flow. In a series circuit the electrons flow in one direction and along one path only while in a parallel circuit the electrons...

    Potential Difference in Electrical Circuit Discussion: We conducted this experiment to test out the relationship of potential differences and currents in series and parallel circuits. We were to indicate the special properties that the potential differences and currents had with both types of circuits. In short, we were to test out Kirchhoff's laws. Before starting the lab, we had to pick three different resistors and we were to calculate the values for the total resistances, potential...
