A charge travels from the positive terminal of a 6�-V battery, through a light bulb, and through the battery back to the positive terminal. The total change in voltage experienced by the charge during this journey is A) -1V B)1V C)-6V D)6V E)0V
A certain fully-charged 9.0 V battery can provide a total of 6500 C to a circuit. How much energy does the battery store when fully charged? (Note that the battery can store the amount of energy equal to the amount of total work it can do in pushing all of that charge through the entire voltage landscape of the circuit.)
1) A particular 12 V car battery can send a total charge of 84 A h (ampere-hours) through a circuit, from one terminal to the other. (a) How many coulombs of charge does this represent? (Hint: current = ) (b) If this entire charge undergoes a change in electric potential of 12 V, how much energy is involved?
A pure electric car is designed to operate with 12 V battery with a total energy of 2.00×10^7 J stored when it is full.
