Series and parallel circuits, venn diagram

  1. 1. Compare and contrast between a series and parallel circuit.Instructions:1st : Use the Venn diagram to list the ‘similarities’ and ‘differences’ between the two circuits.2nd: Discuss and compare your points with those of your peers at your table. (7 minutes)3rd: Now check your points with those on the board. Do you need to add/correct any of your points?4th : Your answer needs to be in two paragraphs. In one paragraph you explain the similarities. In the next you explain the differences.5th: Use the linking words from the chart provided to help you write your paragraphs.6th: Some students are then asked to read out their answers.
  2. 2. List the similarities and differences between a series and parallel circuit. Differences Differences Series Circuit Parallel Circuit Similarities
  3. 3. Differences Differences Series Circuit Parallel Circuit one pathway two or more pathways current same anywhere Similarities current splits- passes in the circuit through pathways -adds up againvoltage shared in ratio converts electrical voltage across each to resistance energy to light, pathway equals heat, sound etc supply voltage resistance adds up- draws less current total resistance less-battery lasts longer than the least resistance - current drawn is less one bulb fuses, -battery life short circuit incomplete one bulb fuses, the others still go Brightness of bulbs less because P = IV Brightness of bulbs more
