Question

1. circuit breakers and fuses are connected in which of the following circuit configurations?

series

parallel

either series or parallel

neither series nor parallel

Explanation:

Analyze safety device function

Safety devices must interrupt current flow to protect the entire circuit.

Determine connection configuration

Using the Series Circuits knowledge point

$$ I_{\text{total}} = I_{\text{device}} = I_{\text{load}} $$

To stop all current, the device must be in series.

Answer:

• (A) Series (Correct answer)
• (B) Parallel
• (C) Either series or parallel
• (D) Neither series nor parallel
