R1 is in series and R2, R3 are in parallel connection.

So the equation to calculate the total resistance is

R1+(1/1/R2+1/R3)

This program calculates the equivalent resistance between A and B of the circuit using the values of R1, R2, and R3 entered by the user. It provides a menu interface for the user to enter resistor values and quit the program. The program also checks the validity of the data entered, ensuring that the resistor values are greater than 0. The equivalent resistance is calculated by first finding the resistance of the resistors in parallel (R2 and R3) and then adding the resistor in series (R1) to find the total resistance from A to B

The program uses a do-while loop to continuously ask the user to enter the resistance values for R1, R2, and R3. Before accepting the values, the program checks if each resistor value is greater than 0. If any of the values is less than or equal to 0, the program prints an error message and continues to the next iteration of the loop, asking for the same value again.

Once the user enters valid values for all three resistors, the program calculates the resistance of R2 and R3 in parallel and the equivalent resistance of R1 and R2 and R3 in parallel in series. The total resistance is then displayed to the user. The program asks the user if they want to enter new values and continues to the next iteration of the loop if the answer is 'y', otherwise, it quits.
