In a series circuit, the current through each of the components is the same, and the voltage across the circuit is the sum of the voltages across each component. In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component. If two or more components are connected in parallel they have the same potential difference across their ends. The potential differences across the components are the same in magnitude, and they also have identical polarities. The same voltage is applicable to all circuit components connected in parallel. The total current is the sum of the currents through the individual components. The difference in households is that we run parallel circuits for the simple fact that it would allow us to operate objects with electricity with more functions of off and on, however if we were to run series it would only connect everything to one specific circuit and that would only allow one thing to be turned on one at a time not allowing constant multiples to be on at the same time. In this picture it shows two outlets being used, one is my lamp and the other is my alarm clock/dock. With the parallel circuits given to me it will allow both of them to function and keep going, instead if it were to be a series it would only allow either or to be operated on.

OHMS LAW
For many conductors of electricity, the electric current which will flow through them is directly proportional to the voltage applied to them. When a microscope view is taken, it is found to depend upon the fact that the drift velocity of charges through the material is proportional to the electric field in the conductor. The ratio of voltage to current is called the resistance, and if the ratio is constant over a wide range of voltages, the material is said to be an "ohmic" material. The quantity work has to do with a force causing a displacement. Work has nothing to do with the amount of time that this force acts to cause the displacement. Sometimes, the work is done very quickly and other times the work is done rather slowly. The standard unit is a Watt for the measurement of Power. Both apply to real life simply due to the fact that Ohm's law and power are technically similar in essences to real life applications such as a oven, or a microwave. The units of watts are needed to figure certain amounts for heat and energy in itself. In this picture it is my oven and it works well with this topic because it matches the similar concepts of ohm's law and power in the oven itself. Also included is how the oven is applicable in real life and to put that into words, is simply as a family we all use the oven for everyday use when cooking specific foods that are meant to be in the oven only.

Importance of Electricity
Electricity is very important because it enable us to use machines such as Television sets, ovens, air conditioners and fans which make our life easier. Electricity also enable us to see easily during the night and when in dark places. As we depend more and more on machines to do important work for us, we must provide energy for electronic machines to work. Not only machines, but people need it to warm their homes in the winter, us it to power their forms of entertainment such as TV sets, or use the light electricity provides to move easily in the dark and do things when the sun has gone down. Everything now in the world relies on electricity as the main source of energy and it will be improved from then on. In this picture it is a fan that gives source of air and technically a cooling source. It is only able to function simply if electricity is given to the unit itself. Unless manual energy through movements and such will cause it to operate.

A capacitance is a property of an electric conductor, or set of conductors, that is measured by the amount of separated electric charge that can be stored on it per unit change in electrical potential. Capacitance also implies an associated storage of electrical energy. If electric charge is transferred between two initially uncharged conductors, both become equally charged, one positively, the other negatively, and a potential difference is established between them. The capacitance C is the ratio of the amount of charge q on either conductor to the potential difference V between the conductors, or simply C = q/V. A capacitor, also called a condenser, is thus essentially a sandwich of two plates of conducting material separated by an insulating material, or dielectric. Its primary function is to store electrical energy. Capacitors differ in the size and geometrical arrangement of the plates and in the kind of dielectric material used. Hence, they have such names as mica, paper, ceramic, air, and electrolytic capacitors. Their capacitance may be fixed or adjustable over a range of values for use in tuning circuits. In this picture I took it is a TV. The reason i chose to take a picture of this is because of the fact that capacitors are involved into these situations for the TV itself to even turn on and it very so relates to capacitance for the electric conductors to work and se
