Task 1 (15 mins) 1- If the electrical voltage that provided by the ministry of electricity is expressed by the following equation: V= 311 * Sin(314t) Where V is the voltage in V, and t is the time in seconds (s). a. Plot the voltage versus the time using the MATLAB or Excel. b. Show the amplitude peak (maximum) on the plot and write the answer. C. Calculate the period by hand calculation and verify that by measuring that from the plot (Screen shot of the figure with cursor labels that are used to measure the period is required). d. If the voltage is changed, such that amplitude is doubled. Plot the voltage after this change on the same figure. From the resulting figure, explain what is the effect of this change on the voltage amplitude, period, and phase
