What is inrush current when energizing inductive loads, and which mitigation methods are commonly used?

• A. Inrush is a high steady-state current; mitigations include using larger conductors.
• B. Inrush is a high initial current surge; mitigations include soft-start, NTC thermistors, and pre-charge resistors.
• C. Inrush is a low initial current that grows; mitigations include adding more inductance.
• D. Inrush is a high impulse event; mitigations include increasing switching frequency.

Answer: (B)
