7–92 Optimum Fusing A sensitive instrument that can be modeled by the series RLC circuit shown in Figure P7–92 is to be protected by a fuse. The voltage across the capacitor is

The peak current was found to occur at about 13 ms after t =0.
Engineer A suggests a 10-mA fuse; Engineer B suggests a 5-mA fuse; while Engineer C suggests a 1-mA fuse. The criterion is to select a fuse that is closest to the peak value of current expected without blowing. Which engineer is correct? Provide evidence for your decision
