- What voltage must be supplied to a lightbulb with hot resistance 820 Ω if it is in series with a voltage source and needs .35 A to function? (hot resistance is resistance lightbulb has when current is applied) 287 V 224 V 351 V 498.4 VA 1.59-V mercury cell with a capacity of 2.0 A*h is used to power a cardiac pacemaker. if the power required is 0.3 mW how long will the cell last in hours? (hint: first calculate the average current)All household circuits are wired in parallel. A 1140-W toaster, a 300-W blender, and a 50-W lamp are plugged into the same outlet. (The three devices are in parallel when plugged into the same outlet.) Assume that this is the standard household 120-V circuit with a 15-A fuse. (a) What current is drawn by each device? Itoaster = A Iblender = A Ilamp A (b) To see if this combination will blow the 15-A fuse, find the total current used when all three appliances are on. Itotal =
