Q1) Ohm's Law (in electricity) states that the current (I) is proportional to the applied voltage (V).The constant of proportionality is the resistance (R). The resulting equation is: V = IR. Thisequation is re-arranged to: I = (1/R) V. Since this is a linear equation, the plot between V(on the x-axis) and I (on the y-axis) should be a straight line, with the slope being 1/R.In an experiment, the following data has been obtained for current for different values of thevoltage.Voltage123Current0.82.52.94.25.6a)Determine the equation for the best-fit line from this data, by using the method of leastsquares.Equation:Plot the data points, and the straight line representing the equation that you found in partb)'a'. (Note: the best-fit line will not pass through all the data points)c)Use the slope of the line to find the resistance.Resistance:LO

After conducting the signal speed experiment a student has recorded the following data. L₂ (m) 1.5 3 4.5 8 15 30 dt (ns) 6.50 13.72 21.02 38.10 72.20 145.42 L2 is the length of the longer cable in meters and dt is the measured time delay in nanoseconds. The student neglected to record L₁, the length of the shorter cable. After speaking with their instructor, they learn all is not lost. They know the speed of the signal can be calculated based on the distance traveled divided by the time. However, the recorded times measure how much longer the signal had to travel in L2 compared to L₁. A little bit of thought convinces them (correctly) that
