🔍 Key Concepts

• Delayed-action fuse purpose – why we sometimes want a fuse to hold briefly during short, high inrush currents instead of blowing immediately • Inrush current – which types of loads draw a very high current for a short time when first switched on • Protection vs nuisance blowing – which circuit type would most suffer from a fuse that blows too quickly on normal startup

💭 Think About

• Which of these circuits is most likely to have a very high but momentary starting current that is still considered normal operation? • In which circuit would an instantaneous-blow fuse cause frequent nuisance trips even though there is no fault? • For each option, think about how steady the normal operating current is versus how much it temporarily surges when switching on or changing state.

✅ Before You Answer

• Identify which listed circuit type is known for high starting/inrush current compared to its normal running current • Eliminate any circuits where current draw is usually smooth and relatively constant during normal operation • Ask yourself: In which application would you deliberately choose a fuse that waits a short time before opening, so the equipment can start without unnecessary interruption?
