2.8 Power and energy in resistive circuits We now consider the power and energy absorbed by resistors and supplied by sources in more detail. Recall that a voltage drop (a decrease in electric potential) across a circuit element in the direction of positive current flow represents energy absorbed. This is the case when current moves through a resistor.
As the world''s demand for sustainable and reliable energy source intensifies, the need for efficient energy storage systems has become increasingly critical to ensuring a reliable energy supply, especially given the intermittent nature of renewable sources.

This is not the case in circuits containing energy storage elements, i.e. inductors or capacitors, where the voltage is related to the current through a differential equation, resulting in a dynamic response of the circuit. In this type of circuits (dynamic circuits), information on the past is necessary to determine the response at any time.
The value at (t = 0) is 1.2 volts. The wave hits this same amplitude at (t = 2) milliseconds and begins to repeat another cycle. Consequently the period must be 2 milliseconds. The frequency is the reciprocal of this value, and thus (f = 500) Hz. The waveform is shifted to the left which indicates a positive or leading phase shift.
