Unformatted text preview: Inn/in. Basic Engineering Circuit Analysis, 9/E 1 9.95 An inexperienced mechanic is installing a 123i:F battery in a car. The negative terminal has been connected. He is currently tightening the belts on the positive terminal. TWith a tight grip cm the wrench, he runs it sn ﬂlat the gold ring nu his ﬁnger makes cuntact with the frame at ﬂ'ie car. This situation is mndeled in Fig. P9135, where we assLu'ne that the resistance of the wrench is negligible and the resistance of the cmstact is as fullnws: a1 = ammmh = nnun R2 = Rmmms = nnun R3 = em = um: [1 R4 = mem = email What pnwer is quickly dissipated in the gnld ring, and what is the impact of this pnwer dissipation?
