A positive-valued resistance is a dissipating element. It cannot deliver energy even
for a short interval. This can be seen from the equation for power delivered to the resistor.
p(t) v(t)i(t) R [i(t)]

a positive number or zero. Therefore, the power delivered to a
resistance cannot be negative at any t and hence resistance will always consume power.
A positive-valued inductance or capacitance is an energy-storing element. It can
deliver the energy back to other elements. But it can deliver only as much energy as that was
given to it earlier. It cannot generate energy and deliver it. Thus, the energy storage in an
inductance or capacitance cannot ...
