A balloon may easily be charged to several thousand volts. Does that mean it has several thousand joules of energy? Explain.
Solution 28RQ No,to have several thousands joules of energy means it has one coulomb of charge,as one coulomb is relatively large amount of charge.energy is voltage times charge,so you need a coulomb of charge to get several thousands of joules of energy. We can also understand the solution for this problem by distinguish between the electrical potential energy and electric potential.electrical potential energy is the energy it takes to put a charge in a given place.electric potential of a charged particle is the potential energy divided by electric charge of that particle.
