Problem 87

An air conditioner draws 14 A at 220-V ac. The connectingcord is copper wire with a diameter of 1.628 mm. (a) Howmuch power does the air conditioner draw? (b) If the totallength of wire is 15 m, how much power is dissipated in thewiring? (c) If no. 12 wire, with a diameter of 2.053 mm, wasused instead, how much power would be dissipated in thewiring? (d) Assuming that the air conditioner is run 12 h perday, how much money per month (30 days) would be savedhv lisina nn. 19. wire? Assume that the r.nst nf eler.trir.itv is

Monday, March 10, 2014 Time-dependent EM effects  We already discussed that electric and magnetic fields are two side of an electromagnetic field.  The relation between electric and magnetic fields is most important through time-dependent effects 2 Recall Maxwell’s equations ∇· E = ρ/ 0 ∇· B =0 ∇× B = µ J + µ ∂ E 0 0 0 t ∇× E = −∂ B t changing B-field produces E-field and vise versa Electromagnetic induction Start with changing B-field producing E-field 3 Faraday’s Experiments (1)
