Two parallel plates of area Im are separated by 02 m and connected to a 12 V battery as shown below. The plates are arge enough compared to their separation that they may be

In electrostatic systems, a potential difference (i.e., a voltage) always corresponds to an electric field. Is this also true about circuits? Specifically, does the potential difference between the two terminals of the battery correspond to an electric field anywhere? Or do circuits allow us to have "voltages without fields?"

(a) In electron-volts, how much work does an ideal battery with a 37.0 V emf do on an electron that passes through the battery from the positive to the negative terminal? (b) If 7.24 x 1018 electrons pass through each second, what is the power of the battery? (a) Number (b) Number i Units Units

In open heart surgery, a much smaller amount of energy will defibrillate the heart. (a) What voltage is applied to the 8 μF capacitor of a heart defibrillator that stores 44 J of energy? V = kV (b) Find the amount of stored charge in mC. mC = Think & Prepare: The heart defibrillator consists of what electrical component?
