In order to work properly, electricity has to get : 1. To the device 2. Through the device 3. And back to the other side of the battery(or outlet)

Open Switch • Electricity can’t move through. • Device will not work properly!! • Called an Open Circuit!! Closed Switch • Electricity can move through. • Device will work properly. • Called a Closed Circuit!!

Before you move on, remember a couple of things: 1. Voltage determines whether electricity flows or not!! 2. Resistance determines how much!! Discuss the dimmer switch they forgot to use in that Hotel!!

2 Types of Electric Circuits: Series Circuit • Current has only one path to take. • All of the current will travel through each device. • “Cheap” Christmas tree lights. Parallel Circuit • Current has more than one path to take. • All of the current will not travel through each device. • “Expensive” Christmas tree lights.
![Series Circuit In a series circuit if one of the lights goes out what Series Circuit: In a series circuit, if one of the lights goes out, what](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-8.jpg)
Series Circuit: In a series circuit, if one of the lights goes out, what happens to the remaining light(s)? Hence, the “Cheap lights”!
![Parallel Circuit In a parallel circuit if one light goes out what happens to Parallel Circuit In a parallel circuit, if one light goes out, what happens to](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-9.jpg)
Parallel Circuit In a parallel circuit, if one light goes out, what happens to the remaining lights? Hence, the “Expensive lights!!
![Remember this Because Stone Cold Said So What determines whether electricity will or will Remember this: Because Stone Cold Said So!!! What determines whether electricity will or will](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-10.jpg)
Remember this: Because Stone Cold Said So!!! What determines whether electricity will or will not flow? Voltage What determines how much electricity flows? Resistance
![Voltage in Series There are 3 different places that the river in this picture Voltage in Series There are 3 different places that the river in this picture](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-11.jpg)
Voltage in Series There are 3 different places that the river in this picture “drops”. Voltage is highest at V 1!! It gets there first!!! If you want to know the total “drop” in the river, you simply add up the separate “drops”!! Same with Electricity!!!! They do drop the same amount!!
![12 V Loses 4 V The Voltage drops some as it passes through each 12 V Loses 4 V The Voltage drops some as it passes through each](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-12.jpg)
12 V Loses 4 V The Voltage drops some as it passes through each resistor!! Loses 4 V Each light will lose the same Voltage and if each has the same resistance, they will each light up with the same brightness!! But what happens if you add more lightbulbs?
![As you continue to add lights they will get dimmer and dimmer WHY As you continue to add lights, they will get dimmer and dimmer!! WHY? ?](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-13.jpg)
As you continue to add lights, they will get dimmer and dimmer!! WHY? ? ? ?
![Why do lights get dimmer as you add more of them to a series Why do lights get dimmer as you add more of them to a series](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-14.jpg)
Why do lights get dimmer as you add more of them to a series circuit? • As you add more light bulbs, the resistance gets bigger and bigger!! • As resistance gets bigger and bigger, current gets smaller and smaller. • Remember, less current= less brightness!!!
![Voltage in Parallel This river has 3 different branches They all follow different paths Voltage in Parallel This river has 3 different branches!! They all follow different paths,](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-15.jpg)
Voltage in Parallel This river has 3 different branches!! They all follow different paths, but when they join back together, how much has each of them “dropped”? The Same Amount Same with electricity!!!
![12 V Total Voltage Therefore the voltage along any of the paths is 12 12 V Total Voltage Therefore, the voltage along any of the paths is 12](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-16.jpg)
12 V Total Voltage Therefore, the voltage along any of the paths is 12 V. If the light bulbs all have the same resistance, the Current through each will be the same!! Each light will “light up” with the same brightness! What if you add more bulbs?
![1 Bulb Notice the brightness 2 Bulbs Notice the brightness 3 Bulbs Notice the 1 Bulb Notice the brightness! 2 Bulbs Notice the brightness! 3 Bulbs Notice the](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-17.jpg)
1 Bulb Notice the brightness! 2 Bulbs Notice the brightness! 3 Bulbs Notice the brightness! 4 Bulbs Notice the brightness!
![Because each branch of a parallel circuit has the same voltage if the light Because each branch of a parallel circuit has the same voltage, if the light](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-18.jpg)
Because each branch of a parallel circuit has the same voltage, if the light bulbs have the same resistance, the same amount of current will flow through each. They will always be the same brightness!! WHY? ? ?
![Why do lights NOT get dimmer as you add more of them to a Why do lights NOT get dimmer as you add more of them to a](https://slidetodoc.com/presentation_image/8e602fb792dac1ad8add1974b46d3a6d/image-19.jpg)
Why do lights NOT get dimmer as you add more of them to a parallel circuit? • As you add more light bulbs, the resistance actually gets smaller and smaller. • As resistance gets smaller and smaller, current gets larger and larger. There’s more of it. • Enough to go to that other path without changing the brightness!!
