Question 1a) In a closed circuit, an electric current of intensity i goes through a resistor ofresistance R. The electric potential at the edges of R is measured to be V. Ifnow we writewould this generally be the definition of the resistance quantity R, or theexpression of Ohm's Law? Explain.b) We define the resistivity (via the familiar notation) asEp=Thus show that the resistance R can be written as,R = p-Ahere L is the length of the resistor, and A is the cross-sectional area of it. c) Let J the current density (i/A). Express J in terms of the electron density n(electrons/m?), the electron drift velocity va, and the electron charge e.d) Show that the resistivity can be expressed (via the familiar notation) as,mne'there m is the electron mass; t is the period of time that elapses between twosubsequent collisions, the electron undergoes with copper nuclei throughoutits chaotic motion in the body of copper (supposing that the current carryingcable is made of copper). Hint: Write F=eE, i.e. the electric force reigning onthe electron. Write also the acceleration a=F/m, an electron is subject to,based on the Newton's law of motion.

The table shows the values for the current, I, in an electric circuit and the resistance, R, of the circuit. Solve; a. Graph the ordered pairs in the given table of values, with values of I along the x-axis and values of R along the y-axis.Connect the eight points with a smooth curve. b. Does current vary directly or inversely as resistance? Use your graph and explain how you arrived at your answer. c. Write an equation of variation for I and R, using one of the ordered pairs in the table to find the constant of variation. Then use your variation equation to verify the other seven ordered pairs in the table.
