Part B (20 marks) A resistor is a passive component that implements electrical resistance as a circuit element. Resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. If several resistors are connected to a battery, the current supplied by the battery depends on the equivalent resistance of the circuit. To find the equivalent resistance, for a series circuit, Req = R1 + R2 + R3 + ....... + While for parallel circuit of two resistors is R1 R2 Ri+R As a programmer you are instructed to write a code with the following specifications to solve for equivalent resisters calculation: 1) For a given data in datafile, input.txt as shown, write a statement to read the file and initialize the input into an array. 2) Send the array to a function that will calculate the resistor in series and print out the equivalent resistor in series. Print the output to the screen. 3) To calculate resistor in parallel, you are required to declare a class. Calculate the equivalent resistance. a) Declare two class data members with public access. b) Declare constructor to calculate the equivalent parallel resistance and print the output to the screen. 12.0 10.2 2.0 Using C++ 3.0 4.2 5.1 10.5 29.2 3.6 Functions input.txt Arrays Array of Objects Pointers Classes Mathematical Equations
