Question 232822: three resistors with values of 1000 ohms, 2200 ohms and 3900 ohms are wired in parallel.To find the total resistance one must add the reciprocals.In the book I am studying the formula to solve is given as:
1/R = 1/R1 + 1/R2 + 1/R3 = 1/1K + 1/2.2K + 1/3.9K = 1/584.5, therefore R = 584.5 ohms
Can you show me how this answer is computed in long hand?
