Series and parallel circuits, venn diagramPresentation Transcript
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.
List the similarities and differences between a series and parallel circuit. Differences Differences Series Circuit Parallel Circuit Similarities
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
