要英文回答.Explain,in terms of energy,the difference between potential difference (p.d.) andelectromotive force (e.m.f.). 答案 Potential Difference is the difference in electric potential energy per coulomb of charge at one point of a circuit compared to the charge at another point in a cir...
We measure the potential difference in volts (which has units of joules per coulomb). The voltage in an electrical circuit controls the current in combination with the resistance. The voltage can be looked at as exerting an electric force on a positive charge (or a negative charge in the opp...
where the first term corresponds to the electrostatic energy of the circuit, Ng = CgVg/(2e) being the reduced gate charge, and where the second term accounts for the energy cost of a phase difference θ across the Josephson junction and is responsible for the tunneling of Cooper pairs. In...

major variables are voltage and current. Voltage, thepotential energyvariable, is sometimes calledpotential. Voltage applied to a circuit elementcausescurrent to flow through that element. Voltage is the push behind current. It is defined as the potential energy with respect to an electric charge: ...
The last important contribution to a FF is the electrostatic interaction between atoms, which is calculated using a Coulomb potential that depends on the distance rij and the partial charges of the atoms qi and qj as well as contains the permittivity of vacuum ɛ0. With Eqs. (3) and (...
Potential energy may also refer to other forms of stored energy, such as energy fromnet electrical charge, chemical bonds, or internal stresses. Examples of Potential Energy A ball resting on top of a table has potential energy, called gravitational potential energy because it comes from the ball...
