Question

Selection of fuse is based on

• A. steady load
• B. Fluctuating
• C. Both (A) and (B)
• D. None of these

Answer 1

The correct option is C

Both (A) and (B)

1. A fuse is a thin electrical wire with a low melting point. The wire breaks up and the current flow stops when a high voltage, or power fluctuation, occurs.
2. As a result, fuse selection is influenced by both stable and variable loads.
3. Fluctuation is defined as when the voltage is very high or very low, causing the electrical device to act in order to manage the current and, at times, stop the current flow.

Hence, option C is correct.
