1 Electricity Notes 3 Objectives
2 Series Circuit There is only one path for the current to travel. bulbs connected in series; when one goes out, they all go out.
3 As you add more bulbs, the brightness of the bulbs decreases. (voltage is affected) Adding more bulbs increases the resistance thereby decreasing the total current in the circuit.
4 Example: Christmas Lights
5 Parallel Circuits A circuit with several different paths. Bulbs connected in parallel; when one goes out, the others are unaffected.
6 As you add more bulbs, the brightness is unaffected. (voltage is unaffected) Resistance does not increase. No current is created or destroyed only split up.
7 Adding resistors in parallel will decrease the total resistance. This will increase the total current leaving the battery.

9 Series Circuit Parallel Circuit # of Pathways Effect of removing a load Voltage drop Current Resistance Connecting cells to form a battery
10 Series vs. Parallel Circuits Flashlight: the cells (batteries) are connected in series. By connecting them in series, higher voltage and therefore a larger current, resulting in a brighter light. If the cells were connected in parallel, the light would be much dimmer, but the battery would last longer Lighthouse: cells are connected in parallel and therefore have a much longer lifespan, reducing maintenance. Important for circuits in remote locations.

12 Technologies for safe use of electricity
13 Circuit Breakers Act as a switch that can cut off all power coming in to your house.
14 Fuses Contains a metallic conductor that melts when excessive current heats it up.
15 Grounding Terminal Allows excess current to flow in to the ground instead of giving you a shock.
16 Electrical Energy The ability to do work Measured in Joules (J)
17 Electrical Power The rate of change in electrical energy The rate at which work is done or energy is transformed. Measured in Watts (W)
18 Electrical Energy Costs Depend on 3 factors: 1.Voltage drop 2.Electrical current 3.Time
19 Power Rating A measurement of how much electrical energy an electrical device consumes for every second it is in use.
20 Calculating Energy Consumption E = energy transferred (J) P = power (W) t = time (s) Mathematical triangle
21 Energy Consumption Page 308
22 Paying for Electricity Power is measured in kw h Complete 9-2 B pg. 310
23 Careers related to Electricity Electrician Photocopier technician
24 Electrical Efficiency Electrical energy may be converted to other forms such as: 1.Light 2.Heat 3.Sound
25 Efficiency of an Electrical Device Efficiency is the % of energy that is converted to a useful form. Efficiency = useful energy output x 100 input Complete practice problems pg. 318
26 Incandescent lighting vs Fluorescent lighting An incandescent lightbulb left on for 10h/week uses 7 kw-h of energy to supply 0.4 kw-h of light. A compact fluorescent bulb uses 2 kw-h in the same amount of time to supply the same amount of light. Calculate the efficiency of each type of lighting.
27 Answer Incandescent: 0.4 kw-h / 7.0 kw-h x 100 = 6% Efficiency Fluorescent: 0.4 kw-h / 2.0 kw-h x 100 = 20% Efficiency
28 EnerGuideLabels Details how much energy an appliance uses in a year and compares to other appliances.
29 Reducing Electrical Consumption Improve insulation of home Turn off lights when not in use Use energy efficient light bulbs Air dry clothes when possible
30 Energy Generator Electrical generator (made up of a coil of wire and a magnet)
31 Electrical Generating Stations 1.Hydroelectric 2.Thermal 3.Nuclear See pg. 327
32 Getting Power Transformers are electrical devices that change voltage so that it can be used by homes. (120 V and 240V)
33 Problems 1.Safety 2.Cost of production 3.Degree of environmental impact
34 Alternate Energy Sources Wind generators
35 Solar energy
36 Fuel cells
