1 Circuits Ch. 35 in your text book Objectives Students will be able to: 1) Draw schematic symbols for electrical circuit components 2) Calculate the equivalent resistance for a series circuit 3) Calculate the equivalent resistance for a parallel circuit
2 Electrical Schematic Symbols Wire Capacitor Resistor + - Battery Switch
3 Circuits Circuit - path or trip around something In order for a circuit to be created, electrons must have a complete path that lets them return to their starting point. What happens when a water pipe is disconnected or if an oil pipe gets broken? What happens if there is an unattached wire in a circuit? Unlike fluids, electrons will only flow if they have a complete loop in which to travel
4 Circuits Open Circuit circuit that does not make a complete loop + - Closed Circuit circuit that does make a complete loop Short circuit a circuit that has an unintended path through which all the current flows short
5 Example: Circuits
6 Circuits Time for the circuits lab

16 Series Circuits Summary of the rules for series circuits: The voltages across each of the resistors have to add up to the total voltage of the battery V T = V 1 + V 2 + V 3 + The current will be the same through each resistor in series I T = I 1 = I 2 = I 3 = The sum of each resistor yields the equivalent resistance R T = R 1 + R 2 + R 3 +

20 9V Parallel Circuits V T = V 1 = V 2 = V 3 = 0 V -Voltage is like how much gravitational potential energy the water has. Each water fall had equal amount of potential energy -Voltage across each level parallel to the battery has the same voltage as the battery
21 Parallel Circuits 9V 0 V - Current is how much water is flowing through over the waterfall - Each waterfall can have a different current, but they are fed by the same river
22 Parallel Circuits I T = I 1 + I 2 + I 3 + I T =? 9V 3 A 3 A 3 A 3 A 0 V The current gets split before it goes over the fall. Similarly, the current in the circuit gets split between each resistor.
