Is instantaneous power ever negative

WitrynaInstantaneous power is the product of the instantaneous voltage across a circuit element and the instantaneous current through it: $$ p(t) = v(t) \; i(t) $$ The above expression defines power at any instant of time and is the rate at which an element absorbs energy (in watts). ... When p(t) is negative: Power is absorbed by the source ... Witrynaa) When P < 0, then AC source’s instantaneous power output can be negative. b) The average power output cannot be negative as $P_{av}>0$.
