Basic Engineering Circuit Analysis [EXP-40319]

An electric lawn mower requires 12 A rms at 120 V rms but will operate down to 110 V rms without damage. At 110 V rms, the current draw is 13.1 A rms, as shown in Fig. 9.35. Give the maximum length extension cord that can be used with a 120-V rms power source if the extension cord is made from
1. 16-gauge wire (4 mΩ/ft)
2. 14-gauge wire (2.5 mΩ/ft)
