Question
Create a Circuit class that uses three data members to store the resistance, input voltage, and current of a circuit. The Circuit class also has the following member functions: A constructor with arguments to initialize data members A function that computes and returns current (input voltage divided by resistance) A function that displays values of resistance, input voltage and current Create an Amplifier class that inherits all members from Circuit except constructor (cannot be inherited). In addition to the inherited members, the Amplifier class has some specific members: A data member gain A constructor with arguments to initialize data members A function that computes and returns an output voltage (input voltage multiplied by gai n) a function that returns gai n Design the main() function to instantiate an object of the Amplifier class and than use this object to call all member functions.Explanation / Answer
