Final answer:
A Class B, Style W notification circuit requires 2 conductors (wires). Two conducting paths are necessary for a complete circuit to enable current flow from a voltage source to an electrical device. For determining the number of resistors removed in a modified circuit, additional information about the original configuration and voltage source is needed.
Step-by-step explanation:
The question is on the topic of electrical circuits, specifically focusing on the number of conductors used in a Class B, Style W notification circuit. The number of conductors (wires) used in a Class B, Style W notification circuit is 2. In general, two conducting paths are needed from a voltage source to an electrical device to provide a complete circuit for current to flow. This is analogous to a scenario in a car where one battery terminal is connected to the metal body, which enables a single wire to supply current to electrical devices, while the body acts as the second conductor.
To answer the follow-up question about the circuit with 1.6 kΩ resistors: if by removing some of the resistors the total current becomes 24 mA, you need to know the original configuration and voltage source to determine how many resistors were removed. Without this information, the question cannot be accurately answered. However, if you provide me with the initial total current and voltage, I can guide you through the steps to calculate the number of resistors that were removed based on Ohm's law and the principles of parallel and series circuits.
