Section 22.2 Practice Problem #31 Solution:
E (charge) = (1.3)IVt = (1.3) (55 A) (12 V) (1.0 h) = 858 Wh = 0.858 kWh = 3088800 J
E = Pt = IVt --> t = E/(iV) = (858 Wh)/(7.5 A * 14 V) = 8.2 h = approximately 29000 s
E (charge) = (1.3)IVt = (1.3) (55 A) (12 V) (1.0 h) = 858 Wh = 0.858 kWh = 3088800 J
E = Pt = IVt --> t = E/(iV) = (858 Wh)/(7.5 A * 14 V) = 8.2 h = approximately 29000 s
