Problem 3 An electric system is rated 15 kVA, 240 V at a 0.5 leading power factor: a) Determine the impedance of the system in rectangular form. b) Find the total resistance and the total reactance (inductive or capacitive) within the electric system. (Assume that all elements are in series.) c) Find the average power delivered to the system.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
