Problem 1: Resistors From Electricity and Magnetism 101 course it is known that resistors can be connected in series and in parallel. Suppose we have a resistor with resistance Ro (possibly a system of resistors with the total resistance Ro), and would like to connect a new resistor with resistance R to it. Then the new resistance R, of the system will be given by R, = Ro + RI, if connection is in series, and RR R = Ro + R if connection is in parallel. One can have a system containing many resistors connected both ways, and it is convenient to have a class that allows us to calculate the resistance of the whole system by adding resistors one by one. Write a simple class named 'Resistor' with only one attributer representing the value of resistance. Adding a new resistor is achieved by method 'add_res', having external parameter 'in_series' that assumes either True or False depending on how the other resistor is attached (True means that the new resistor is connected in series). This method should also return class Resistor but with new total resistance. Do the following (all resistances are in Ohms): Create a resistor with resistance 1 Ohm Create a resistor with resistance 5 Ohm Add them in series and output the new value Add to the system the 3 Ohm rsistor in parallel and output the new value Add to the system the 10 Ohm resistor in series and output the new value Add to the system the 4 Ohm resistor in parallel and output the new value
