Find Law Schools and Degree Information By StateCongratulations on taking the first step towards becoming a lawyer. If the law school you are planning to apply to is not on this list, the information provided for the above schools can usually be found in the admission requirements section of the respective school’s website. The purpose of this session is to teach you the basics of electricity and introduce the concepts of potential difference, current, resistance and power. The nucleus contains positively charged protons and atomic particles with no charge known as neutrons. Orbiting the nucleus, rather like the planets in the solar system orbit the sun, we have electrons.
Thus we can also define a conductor as being a material that allows electrons to move easily between atoms.
Conversly an insulator is a material that inhibits or completely stops the flow of electrons. In order to get the electrons to flow in significant numbers and in the the same direction we need some type of electrical force. Electrons are attracted to the postive terminal if we provide a path through which they can flow i.e. The  difference in the amount of positve ions and spare electrons available at each of the two terminals determines how many electrons can flow through the circuit.
We can use this very important law to calculate the resistance, flow of current, voltages and power dissipated for any circuit containing a power source and resistors. The total voltage supplied by the power source must be used up by all of the components in the circuit (including the power source itself). In session 2 you will make and test some simple circuits using just one component, the resistor.


Below is an illustration of a resistor and an example of how to read the resistor colour code.
We can see from the illustration that the current, rather like a river, flows from the source. The total resistance of this circuit is always lower than the value of its lowest resistor. Assuming the circuit has a maximum power dissipation of 1.25 watts choose suitable voltage from the table.
Save all of the data for this assessed task including all of your calculation, screen dumps showing the simulated values and most important. Make sure you simulation and calculations agree. You are not penalized for incorrect answers and all questions in a section are weighted the same. To achieve electrical balance the number of electrons orbiting the nucleus must match the number of protons in the nucleus.
Heat causes random electron displacement and is one of the main causes of electrical noise and interference in electrical circuits. When electrons flow in this way they do work, the amount of work done is proportional to the amount of electrons flowing. This is known as Faradays law of electromagnetic induction and we will becoming very familiar with it later on in our studies.
A circuit has 2 terminals (ends), one terminal produces lots of positive ions (the positive terminal), the other terminal has lots of spare electrons (the negative terminal). Electrical and electronic engineers call this the potential difference between 2 points in a circuit. Electric current (the flow of electrons) happens when, and only when a potential difference exists between 2 points in a circuit.


This is your check, if your total volt drops do not come to within 1% of the applied voltage then you have made an error and will need to check your work. Then splits up and flows through each branch before joining back and returning to the source.
To find the power dissipated calculate the voltage across the bank that the resistor is in, square that voltage and the divide it by the resistance of the resistor. Your correct answers are converted to correspond to an LSAT scale that ranges from 120 to 180. They are weakly attracted to the protons in the nucleus and easily displaced. When an atom loses an electron we say it has become a positive ion. The amount of electrons flowing in a circuit is measured in amps and is rather confusingly given the letter I in equations.
Basically you take the product of 2 resistors (multiply their values) and divide the product by the sum. It only works for 2 resistors at a time. A score of 120 represents the lowest possible score while 180 represents the highest possible score. A statistical procedure is used to calculate scores based on minor differences in difficulty between test forms.
Too many factors affect a test’s ability to be an extremely accurate predictor such as motivation, work or family responsibilities, motivation and physical or mental health. However, the LSAT has proven that that it compares quite well with other tests used in other fields of graduate and professional study.
