Application Of An Electrical Circuit

In Part 1 of the lab, a solar cell was created and tested for its capability to conduct electricity. After researching the processes that contribute to the conductive property, it was found that the oxidized substance is the dye, as it donates an excited electron to the titanium oxide. Consequently, titanium oxide is reduced before it donates an electron to the cathode. The electrolyte solution was found to replenish the dye with electrons so it could continue to act as a reducing agent.

What is an electrical circuit? How can you manipulate components and design a circuit that will do what you want it to? This guided activity will introduce you to some components, tools, and concepts that are fundamental in electronics. It will allow you to investigate and discover:

If they are thicker or shorter this will change the rate of electrolysis over time. The larger the electrode, the more copper can be deposited on it and faster.

When all quantitative data has been collected and recorded, use the equation below to calculate the average electrical potential difference, or Average E_Cell of each variation of Copper Chloride.

The EPA estimates Americans purchase nearly 3 billion batteries each year (D., 2009). A battery is also known as a voltaic cell, and the energy generated and stored by a battery is actually a result of chemical reactions and not mechanical motion. Batteries are contained in nearly every common electronic device, ranging from small devices like smartphones to larger scale products like automobiles, and chemistry is the driving force behind the function of these batteries.Batteries consist of galvanic cells that carry out the production and storage of electrical energy from chemical reactions. The chemical reactions going on inside of the battery are between the oxidant and reductant of Copper and Zinc metals in there Copper-Zinc Voltaic

Chem Speech – Daniel George From the roots of the HSC Chemistry course, we are conditioned to the concept of a Galvanic Cell. It is essentially a circuit containing a Positive Cathode where reduction reactions occur and a Negative Anode, where oxidation reactions occur. Galvanic Cells operate with the basic principles of converting chemical energy into electrical energy via spontaneous reactions at the Anode and Cathode. However, today we are looking Electrolytic cells. These operate with the function of converting electrical energy into chemical energy, forcing Chemical reactions to occur and contain a Negative Cathode and a Positive Anode.

The two types of electrical circuits are series and parallel. Series circuits provide only one pathway of current flow, while parallel circuits provide multiple pathways of current flow. Unfortunately,

A battery is a gadget that changes over synthetic vitality into electrical vitality. Every battery has two terminals, an anode (the positive end) and a cathode (the negative end). An electrical circuit keeps running between these two anodes, experiencing a synthetic called an electrolyte (which can be either fluid or strong). This unit comprising of two anodes is known as a phone (regularly called a voltaic cell or heap). Batteries are utilized to control numerous gadgets and make the sparkle that begins a gas motor.

Voltage represents electric potential energy per unit charge. If a unit of electrical charge was placed in a location, the voltage indicates the potential energy of it at that point. Basically, it is a measurement of the energy contained within an electric circuit or electric field at a given point.

Throughout this experiment we looked at basic principles of DC circuits and electrical currents by measuring the voltages and currents in simple currents. We used Ohm’s law R=V/I and R=E/I and the values of current and voltage to find the resistance of an electric circuit. We also found that the SI unit of volt are Joules/Coulomb and that power is measured in Watts.

In the book, “The Circuit” by Francisco Jimenez, some examples are given on how family and culture can influence one’s life. Family and culture can negatively affect a person’s life because in the narrator’s case, it can cause them to move away from their friends or work hard to support their family. For example, “As the last days of August disappeared, so did the number of braceros. Sunday, only one—the best picker—came to work. I liked him. [...] That Sunday was the last time I saw him. [...] The thought of having to move to Fresno and knowing what was in store for me there brought tears to my eyes” (Jimenez 2 and 5). In other words, the narrator had to leave because the harvesting season was over and they had to find another place to work.

Those three parts are: The anode (the negative part of the battery), the cathode (the positive part of the battery), and the middle part of a battery, the electrolyte [a chemical compound, which allows the flow of electric charge between the positive (cathode) and the negative (anode) part of the battery]. For example when an electric circuit is connected to the battery, a chemical reaction occurs on the electrodes. Because of that chemical reaction, which is inside the battery, the anode builds up a surplus of electrons. That creates an electrical difference between the anode and the cathode. Then, the electrons want to rearrange themselves and then displace the electrons in the cathode. The electrolyte, which is in the middle of the battery, makes sure that no electron can travel directly in cathode. At the end, when the circuit is closed, with a conductive path between the anode and the cathode, the electrons will be able to travel into the cathode. There is an example of an electric circuit with a battery like this, under this text. After a long period of time, a battery cannot supply electricity anymore because over time, that process alters the producing in the anode and the
