### Circuits Power Point

1. 1. Mr. Baldwin Parallel and Series Circuits
2. 2. <ul><li>All elements connected consecutively </li></ul><ul><li>Removing one light breaks circuit </li></ul><ul><li>Same current in both lights </li></ul>Series Circuit
3. 3. How to Wire a Series Circuit!
4. 4. <ul><li>Elements connected separately </li></ul><ul><li>Remove one light, the others still work normally </li></ul><ul><li>Voltage the same across each element </li></ul>Parallel Circuit
5. 5. How to Wire a Parallel Circuit!
6. 6. Lets watch a Video!:
7. 7. <ul><li>Arrows show direction of current flow </li></ul><ul><li>Voltage across each resistor element is equal </li></ul><ul><li>Current varies based on resistance, V=IR, so I=V/R </li></ul>Voltage/Current in Parallel
8. 8. <ul><li>All lights (resistors) share the same current flow </li></ul><ul><li>Total resistance = sum of all resistors (lights) </li></ul><ul><li>R Total =R1+R2+R3+R4 </li></ul><ul><li>V=IR, so I=V/R Total </li></ul>R1 R2 R3 R4 Current and Voltage in Series
9. 9. <ul><li>Voltmeter- measures voltage (V) </li></ul><ul><li>Ammeter- measures current (I) </li></ul><ul><li>Multimeters measure both! </li></ul>Multimeters!
10. 10. <ul><li>Pass out activity worksheet </li></ul><ul><li>Questions on worksheet? </li></ul><ul><li>Get materials and get in groups </li></ul><ul><li>GO! </li></ul>Time to start!
