More Electricity

The last thing we did with electricity is solving the currents, resistance, and voltage using multimeters and and by using mathematics. The first couple thing you need to know is that you measure voltage across what you are trying to measure other wise known as making a bridge. And you measure current through the multimeter arranged in the path before the object you are going to measure. Make sure you do this correctly with the multimeter or else Mr.Blake will make you think you broke it. To find this mathematically there is four steps. First of all you must find the REQ which is found by adding together all the resistors over 1. Then you find the Ibatt. which is found by dividing total voltage divided by REQ, the answer is then in amps. The next to steps is to find the voltage and current which can differ depending on the circuit.

Capacitors, Resistors, & Voltage

 The first thing we learned about in this class is about electric potential and electric potential energy. Electric potential energy is stored energy of an object in an electric potential field. Electric potential is the amount of electric potential energy divided by charge. Another thing we learned about is voltage, voltage is the electric potential difference between two points. the last thing we learned about is capacitor. Capacitors are used to store energy, it sores lots of voltage but not a lot of charge. An example of this is the big green boxes you see around campus that says high voltage on them. In class we used something that created huge amounts of voltage but not a lot of charge.

Electricity 2

In physics we are still learning about electricity. The most recent thing we learned about is the combination circuits. It consists of both series and parallel circuits. These circuits are also called "inception" according to Mr. Blake. When the circuit splits into parallel then the current splits between each part of the parallel part of the circuit. When all the parallel parts of the circuits meet the current goes back together therefore the initial is the same as the final current. We also learned how to draw schematic diagrams. It is a simpler drawing of a circuit using only three symbols. A battery is represented by a short and long line, a resistor is represented by a squiggly line, and a cable is represented by a line.

So far in class we have been learning about electricity. When electric companies send electricity to houses, they send it in high voltage to reduce the amount of lost electricity when they send it. A series circuit has constant current. I also learned that if you plug too many appliances (resistors) in one place of your home i.e. the kitchen your breaker box will flip. This will disable the current to flow through the certain area. When there is too much current going through a fuse then the fuse will burn out causing the continuity of the circuit to diminish.

Home Electricity

In the pat few weeks we have been working on electricity and circuits. In class we learned that there were two types of circuits, parallel and series. We learned that our homes were wired to have parallel circuits. Parallel circuits enabled the household to be able to power everything at the same amount of watts. Unlike a series where the resistors share the power. So what we did was we had a take home lab to complete over the super bowl weekend. it was to find common things around our house or dorm that used electricity. We then took a look at the label and calculated how much amps watts and ohlms each resistor took. We were then given a challenge to see how much money we could save by saving electricity. We were suppose to ask our parents to keep the change for the first month. Since I live int he dorm I did not but did try to save some electricity.

Conservative Energy

In class we learned about multimeters, volts, and amps. During class we used the multimeter to measure the current flow of electrons through parallel and series circuits. We learned about the items that used the most energy in our households. Some of these items include refrigerators, heaters, and dryers. Things that heat and cool things use a lot of energy to do so. So our challenge was to lower our electricity bill per month in our household. Since I live in the dorm this challenge didn't work too well for me. But I can  try and save energy here as well, the most I can do is save money. We can all do simple things to save money such as turning off lights and fans and unplugging accessories when they are not in use. Overall it shouldn't be too hard to save your family a little bit of money. We also talked about having solar panels on household roofs to reduce the amount of money and electricity spent.

Charges #3

This is a picture of a normal duracell double a battery. In class we leaned that this battery has a voltage of 1.5V. Many batteries has the same voltage as this one, but the bigger it is the longer the charge lasts. the amount of chemicals differs in the size of the battery, causing it to last longer. In class we hooked it up to a light bulb to make it light, the we hooked the light bulb to a 9 volt battery. The light bulb exploded in less then a second because of the high voltage. We also learned that just because something has a lot of voltage, it does not mean that is dangerous. It depends on how much charge the item contains. For example we used this object in class which generates 100,000 volts, but when you touched it, it did not hurt. We also learned that electric potential does not equal electric poetential energy. The last thing we learned is the electric potential is equal to the amount of electric potential energy per charge.
