samples of static electricity which is a little bit different than electricity still what that means is the electricity is not flowing through a current but instead is just an attraction between negative and positive such as the negative extra ions on that PVC pipe with all those objects it would get close to like a bubble or the plastic really cool video examples of electricity as far as static electricity goes the energy contained within an electric field this energy is called electric energy electric energy is also called electricity electric energy can be transferred or stored from one place to another transfer from one place to another electricity but when we talk about electricity electricity static electricity electricity you should know there are actually two static and current current electricity is the flow of electrical energy is called current electricity charges is called the current charges is that carry electrical energy or electricity with them electricity is used to power electrical devices such as the pier build this current do you have yo travels through the wire your output touches your light bulb and then it traveled back to that sorcerer have to be a loop-the-loop it won't work anymore set order for charges to travel this path is called a circuit or such as that battery electrical device the power source provides a force or pressure to push the current electrical device uses Seco energy so one of the way that we're going to be using current electricity to safest way for us to use it is the form of a battery solar battery generates electricity by pushing the current through a circuit is the kapos so the problem is part that sticks out animal animal Tramadol is it a no and that's the last part of the battery inside are electrolytes the electrolytes are are sore form of energy when we talk about 15 electrolytes that are desks set a timer and then inside the battery contains electrolytes the positive and negative particles terminals are connected to the wire the circuit reactions occur inside the battery the negative charges the electrons to build up at the negative terminal the electrons move from the negative terminal to generate the current a positive place so you might start off in a negative place that you always want to travel and get to that positive place circuit to not have breaks it must be at continuous loop a circuit with outbreaks is called a closed circuit the power source in the electrical devices must be attached to the circuit has a path of travel from the negative term positive terminal battery for battery with that being said you can break the current in that turn the lights off which comes into play so if there is a break in the circuit with a circuit is not closed in other words it's not a continuous loop flow and this is called an open circuit you didn't have that the Jimmy sad what you had is it started here they went through here so light bulb to light bulb will not come on so if wire's are not attached the power source correctly you don't have one wire going into the negative one wire going into the you're going to have an open circuit if they are not correctly attached to the appliances it's going to be an open so here are coming from the negative and one positive noticed this break here and this break causes it to be an open circuit and if you have an open circuit control this with a switch what does switch on the lights turn off when you flip the switch a circuit is open or is open Market is open and the current will not flow but when the switch is closed circuit is closed and the current will flow so again close think of it kind of like a drawbridge gate if it is up the car can't go down the road there's electrons can travel through that current draw bridge is closed electrons can get through in a white school versus insulators when we talked about energy to go through electricity go through conductors metals are great conductors just like they were ER for electricity as well or silver aluminum are all common factors also a good conductor are craters on the other hand are the exact opposite they don't let energy go through whether it's heat or electricity so insulators are materials that do not allow electricity to flow easily rubber and plastic Slater's electrical wires are with an inflated to keep the current flowing through the wire to prevent electrical shock electric shock occurs when the electric current jumps from a circuit to your body and pain current electric shock so that's the reason why you're not supposed to use pray chords is because when is open slit in it you can actually get shocked because the electrons will travel from those copper wires to your body like the PowerPoint says it could be dangerous it can even kill you if the current is strong enough so that's it for the Mets today the next thing that we're going to talk about the different between the two major types of circuits C major types of circuits are series and parallel circuit the one right after it on the other hand is going to look a little different it's going to look like this like I said in the Gizmo learn the difference between these two and experiment with these two in preparation for the lab
