  1. 1. Circuits
  2. 2. Resistance <ul><li>Length and diameter </li></ul><ul><li>Which hose gave us the most resistance? </li></ul><ul><li>Which gave us the least resistance? </li></ul><ul><li>Video </li></ul>
  3. 3. Current and Voltage <ul><li>Current </li></ul><ul><ul><li>Continuous flow of electricity </li></ul></ul><ul><li>Voltage </li></ul><ul><ul><li>Potential energy between two places in a circuit </li></ul></ul>
  4. 4. Ohm’s Law <ul><li>Ohm set up a circuit with voltage between two points on a conductor. </li></ul><ul><li>Ohm found that length and diameter affect resistance. </li></ul><ul><li>Changing the voltage in a circuit will not affect the resistance </li></ul><ul><li>Formula (p. 61) </li></ul><ul><ul><li>Resistance = Voltage/Current </li></ul></ul>
  5. 5. Circuits <ul><li>Series (p. 64) </li></ul><ul><ul><li>Moves in one path…very simple </li></ul></ul><ul><ul><li>If one light breaks, the rest will no longer work </li></ul></ul><ul><ul><li>Resistors – When more lights are added to a series circuit all the lights become dimmer </li></ul></ul><ul><ul><li>Ammeter is used to measure a current </li></ul></ul>
  6. 6. Circuits <ul><li>Parallel (p. 65) </li></ul><ul><ul><li>Several paths </li></ul></ul><ul><ul><li>Resistors – In a parallel circuit resistance actually decreases </li></ul></ul><ul><ul><li>As new branches are added, the current has more paths to follow </li></ul></ul>
