Can average power be negative

WebSpeed is a scalar, and average velocity is a vector. Average velocity indicates direction and can be represented as a negative number when the displacement is in the negative direction. Average speed does not indicate direction and can only be positive or zero. WebIn a purely resistive circuit, all circuit power is dissipated by the resistor (s). Voltage and current are in phase with each other. In a purely reactive circuit, no circuit power is dissipated by the load (s). Rather, power is alternately absorbed from and returned to the AC source. Voltage and current are 90° out of phase with each other.

WebPower is defined as the rate of doing work, or the limit of the average power for time intervals approaching zero, P = dW dt. P = d W d t. If the power is constant over a time interval, the average power for that interval equals the instantaneous power, and the work done by the agent supplying the power is W = P Δt W = P Δ t.
