💻 Activity: Create a Class for Parallel Circuits

We built a class for circuits in series. Use what you learned last week about circuits with resistors in parallel and what you now know about classes to construct a class for circuits in parallel.

Consider this circuit with 9 volts of energy and three different resistors in parallel.

1. Build a class for a parallel type circuit called ParallelCircuit that

• holds information about a circuit with resistors in parallel and

• calculates the total resistance, current, and voltages across each resistor.

2. Add to the ParallelCircuit class a method that allows the resistance of each resistor to be associated with the circuit.

3. Add to the ParallelCircuit class a method to the class to calculate the total resistance.

4. Add to the ParallelCircuit class methods that calculate the current flowing through the circuit or the voltage across each resistor.

# create a class object
...
    # create a constructor for the ParallelCircuit class
    ...

    # create a method that adds a resistor to an instantiation of the ParallelCircuit class
    ...


    # create a method that sums the list `components` of an instantiation of the ParallelCircuit class
    ...

    # create a method that calculates the current flowing through an instantiation of the ParallelCircuit class
    ...

    # create a method that calculates the voltage across each resistor an instantiation of the ParallelCircuit class
    ...

5. Apply this class to revisit the circuit with 9 volts of energy and three different resistors in parallel that we considered with nested lists last week.

# instantiate the class
...

# construct the circuit
...

# apply the total_resistance method to the instantiation of the class
total_resistance = ...

# apply the circuit_current method to the instantiation of the class
voltage_source = 9  # 9V voltage source
current = ...

# apply the component_voltages method to the instantiation of the class
voltages = ...
