A 120-V circuit in a house is equipped with a 30-A fuse that will interrupt if the current exceeds 30A. What is the smallest resistance that can be plugged into the circuit without causing the fuse to interrupt?

    Rmin = V/Imax = 120 V / 30 A = 4.0 ohm

    Resistance of at least 4 ohms.

    R = E/I = 120/30 = 4 Ω
