Problem 4:The formula for calculating equivalent resistance of a total of n resistors wired in series is:

The formula for calculating equivalent resistance of a total of n resistors wired in parallel is Write a script which calculates the equivalent resistance of n given resistor:s a) The code askes for the values of the resistance of the n resistors as an input vector b) The code asks the user which type of assembly mechanism s/he requests for: serial or parallel c) The code will check the elements of the vector R As soon as if it finds the first resistor with zero or negative resistance, it shows the message "The input data has zero or negative resistance values." stops checking the rest of the elements as well as the exccution of the rest of the code after the warning message is sown. - d) If checking of the elements has passed successfully, based on the type of the requested assembly, the code returns the equivalent resistance e) Run your code for R - [2 -3.1 0 -3.5], serial ii)R 12-3.1 0 -3.5], parallel iii) R [2 3.1 2 3.5], serial iv) R = [2 3.1 2 3.5], parallel
