If an electrical component with a resistance of 35 2 is connected to a 112-V source, how much current flows through the component? Need Help? Read It

A dry cell with an emf of 1.50V and an internal resistance of 0.050 ohms is "shorted out" with a piece of wire with a resistance of only 0.20 ohms. What will a voltmeter read if it is connected to the terminals of the dry cell at this time?

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 =

Six lead-acid type of secondary cells each of emf 2.0 V and internal resistance 0.015 Ω are joined in series to provide a supply to a resistance of 8.5 Ω. What are the current drawn from the supply and its terminal voltage?

(a) Find the voltage drop (in V) in an extension cord having a 0.0650 Ω resistance and through which 5.45 A is flowing.  V   (b) A cheaper cord utilizes thinner wire and has a resistance of 0.340 Ω. What is the voltage drop (in V) in it when 5.45 A flows?V   (c)Why is the voltage to whatever appliance is being used reduced by this amount? What is the effect on the appliance?

The resistance of a bagel toaster is 11 Ω. To prepare a bagel, the toaster is operated for one minute from a 120-V outlet. How much energy is delivered to the toaster?

Diagram of the problem, necessary formulas, clearance and numerical solution. An electric light bulb is marked 40 W - 120 V. What is its resistance when it is lit from a 120 V source?
