Problem 3. (Lastname_Lab2_p3.cpp) Write a C++ program that will take the resistance values of two resistors (R1 and R2) and voltage (V) of the circuit from the keyboard input. The program should calculate and display the values of current (I) a) when the resistors are connected in series and b) when the resistors are connected in parallel. [Hint: I = V/Req, Reg (in series) = R1 + R2, Reg (in parallel) = (R1*R2)/(R1+R2)]. Following is the example test case for the program: Enter the values for R1 and R2: 2 2 Enter the value of V: 4 The value of I in series network: 1 The value of I in parallel network: 4
