Calculating resistance of n devices - JavaScript
In Physics, the equivalent resistance of say 3 resistors connected in series is given by −
R = R1 + R2 + R3
And the equivalent resistance of resistors connected in parallel is given by −
R = (1/R1) + (1/R2) + (1/R3)
We are required to write a JavaScript function that takes a string having two possible values, 'series' or 'parallel' and then n numbers representing the resistance of n resistors.
And the function should return the equivalent resistance of these resistors.
Example
Let us write the code for this function.
const r1 = 5, r2 = 7, r3 = 9;
const equivalentResistance = (combination = 'parallel', ...resistors) => {
if(combination === 'parallel'){
return resistors.reduce((acc, val) => (1/acc) + (1/val));
};
return resistors.reduce((acc, val) => acc + val);
};
console.log(equivalentResistance('parallel', r1, r2, r3));Output
Following is the output in the console −
