Write a C program that uses a function to calculate Rt. The user will be prompted to enter R1, R2 & R3 which will be passed to the function as parameters, do not use global variables or pointers. The values have no specified range for them but if any of the 3 inputs are less than 0, the function should return 0. The main function should then display the calculated value of Rt with 2 decimal places or an appropriate error message.
Write a C
The main function should then display the calculated value of Rt with 2 decimal places or an appropriate error message. (Do not use printf or scanf inside the function ... all input/output should be in main)
Use appropriate message to prompt the user to enter each value.
Three resistors (R1, R2 and R3) are connected so that R1 & R2 are in parallel then in series with R3. Their equivalent resistance (Rt) is calculated using the following equation:
Rt=(R1xR2/R1+R2)+R3
