Question

2. [5pts] 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.

Answer 1

Output of the Equivalent Resistance :

circuit that all Program to calculate the equivalent resistance in a % electrical resistors are connected in parallel input('Enter the number of resistors = zeros (vector_size,1); vector size resistor = 1:vector size resistor (i) end Efor i input E for i = 1:vector size if resistor (i) fprintf('ERROR' ); exit; end end equiv_resistance 1/sum(1./resistor); fprintf'$$$$$$$ fprintf('Number of resistors : %i fprintf ('Equivalent Resistance %f ohms',equiv_resistance); Equivalent Resistance for Resistors Connected in Parallel Gu\u\$$$$ ',vector size)

Equiv_resistor Enter the number of resistors 7 10 30 70 100 50 80 40 Equivalent Resistance for Resistors Connected in Parallel $$$$$$$ $$$$$$$ Equivalent Resistance Number of resistors 7 4.648589 Ohms
