Write a matlab script that can calculate the equivalent resistance in a circuit that all electrical resistors are connected in parallel: . print the title 'equivalent resistance for resistors connected in parallel' on your output. check the size of vector resistor to see how many resistors in the circuit. check each individual resistance to see any 0 or negative resistance. if there is any, print message 'error', then finish the program. otherwise, calculate the equivalent resistance by the equation 1 1 1 1 + r r r r r. 4.8xpt print the equivalent resistance in the format like number of resistor 7, equivalent resistance 9.132 ohms' . try 2 circuits with resistances as [ 90 80 80 -50 100 20 0] and [ 10 30 70 100 50 80 401 . submit script and the results from command window.
