SERIES AND PARALLEL CIRCUITS
Compose a paper describing the rules of voltage, resistance and current (and power) in a DC series circuit and a DC parallel circuit. Explaining how voltage, current and resistance are affected when a short circuit or open circuit occurs in series and parallel circuits.
Paper must be typewritten using reasonable margins and reasonable font and double spaced. Use DIAGRAMS, FORMULAS and CIRCUIT EXAMPLES to support your claims. These may be hand drawn if necessary. So, for example if you claim that current is everywhere the same in a series circuit, the following would support your claim. “In a series circuit, current is everywhere the same so that; I(T)=I(1)=I(2)=I(3)…”
I am looking for characteristics of these circuits. I am looking for formulas. I am looking for diagrams. Ohm’s law should be a part of this paper, but be careful not to repeat yourself. Start with series, then present parallel.
When you are finished, you should have an almost side-by-side comparison of how voltage, current, resistance relate in series and in parallel. You should also have a working understanding of troubleshooting a series or parallel circuit and how shorts and opens affect a series or parallel circuit.
I would suggest the following outline:
1. Ohm’s law (1) and Joule’s Law for Power (2)
2. Series circuits – definition of (3)
a. Voltage(4)
b. Current(5)
c. Resistance(6)

b. Current(14)

5. Short circuit/Open circuit; Parallel (16)

Series and Parallel Circuits
In making humanity understand the laws of electricity and the calculations, there are scientists who devised different laws like Kirchhoff and Joules. Their laws relate current, voltage and resistance. Besides, there are two major connections that are studied. These are parallel and series connections. These two connections vary in their characteristics of current, voltage and resistance (Walker, Resnick & Halliday, 2014). It is these features distinguish the two connections. In analysis presented in this paper, the series and parallel connections are analyzed in terms of current, voltage, resistance, closed and open circuits.
Ohms law
Ohms law establishes the potential difference and how it relates to resistance and current. The law states that "the potential difference across an ideal conductor is directly proportional to the current". When written as an equation, it appears as V=IR where V is voltage, I is current and R is the constant of proportionality called resistance. In this direct proportion, any increase in the current increases the voltage. Similarly when R is higher, the current I is reduced (Walker, Resnick & Halliday, 2014).
Joules law for power
Joules law relates the current to the amount of heating it causes in conductor during the flow. The more current that is released, the more the heat produced. In an equation it is written as; H=I2.R.T. The time it takes for more current flow will also determine the amount of heat it generates. R is the resistance of the conducting material. For this equation to be true, the current is squared.
Series circuits
In a series connection there is a positive to negative connection which sums all the voltages through all the power sources. For the same type of connection there is a similar current through most of the devices.
In the connection above the voltage is summed across all the power sources and the current is held similar. In equations; VT=V1+V2+V3 and IT=I1=I2=I3. Furthermore, the resistance is the sum of the individual resistances across all the devices and is expressed as RT=R1+R2+R3. In the equations, the sum of all the voltages and the currents are represented by VT and IT. The resistance will vary according to the currents produced by each component (Walker, Resnick & Halliday, 2014).
For the series connection above connection a short circuit is one that allows the unidirectional flow of current without any resistance. In such a case the connection has current but no voltage flow. The resistance...
