Calculate Total Resistance in a Series Circuit

You are an electrical engineer working on a circuit design. In this design, multiple resistors are connected in series. To ensure the circuit functions correctly, you need to calculate the total resistance of the circuit. The total resistance is the sum of all the resistors connected in series. Your task is to write a function that calculates this total resistance based on the resistors' values.

Instructions:

• Write a function named calculateTotalResistance that takes one parameter:
  • resistances: An array of numbers representing the resistance values of individual resistors in ohms.
• The function should return the total resistance of the circuit in ohms, which is the sum of all the resistance values in the array.

Note: Only use the map, filter, or reduce methods, or a combination of these methods, to solve the problem. Do not use loops to iterate or perform the operation.

Example 1

Input: calculateTotalResistance([5, 10, 15]);
Output: 30

Example 2

Input: calculateTotalResistance([2.5, 7.5, 10]);
Output: 20

Example 3

Input: calculateTotalResistance([]);
Output: 0
