The programming language is basic C. I'm having trouble with the (1/r1 + 1/r2 + 1/r3)^-1 formula.

Ca Figure 1: Resistors in (a) in series (b) in parallel The formula for calculating equivalent resistance of three resistors is given below (see Figure 1 for series and parallel connections) Series: Rs = R1 + R2 + R3 Parallel: 1- 1 1 + Write a program that prompts the user to enter values of R1, R2, R3 and V. Then compute the current through the resistors for both series and parallel connections. The current should be carried out to 2 decimal places Sample Output Enter values of R1, R2, and R3 (in Ohm): 3 4 5 Enter the Voltage: 5 Current through resistors in series: 0.42 A Current through resistors in parrallel: 3.92 A
