🔍 Key Concepts

• Function of a fuse in an electrical circuit (it protects the circuit by melting when current is too high) • The effect of resistance at connections such as loose or corroded clips • Difference between a fuse that is too large vs conditions that make a fuse open (blow) more easily

💭 Think About

• Which option would increase heat at the fuse connection and make it more likely to melt? • Which options would actually make a fuse less likely to blow, even if they are bad practice? • Think about how poor connections versus solid, tight connections affect current flow and localized heating.

✅ Before You Answer

• Verify which condition would cause excessive heat at the fuse or its holder • Check whether an oversized fuse is more likely to blow or less likely to blow for a given overload • Consider if ambient temperature alone, when extremely low, would reasonably cause a fuse to open in a normal circuit
