Question

A charge of +1.00C is moved from an equipotential surface for 3.14 m. How much energy did it take to do this? _______________ A charge of +1.00C is moved from an equipotential surfce at +1.00 V to a second equipotential surface at +3.00V. What is the smallest amount of energy it could take to do this? _______________ A parallel plate capacitor has a charge of -1.00C on one plate (and obviously +1.00C on the other plate). The capacitor has a capacitance of 0.25F. What is the absolute value of the voltage caused by this charge? (i.e., |V|) _______________ Equipotential surfaces are shown in the figure. An electron is moved from point A to point H. Remember that the change in Energy is given by delta U = q x delta V. What is the change in energy of the electron in Base SI units? _______________

Explanation / Answer

smallest amount of energy = q(V2 - V1)

                                           = 1 * (3 - 1)

                                           = 2 J
