WebAssuming the passive sign convention, (1) The instantaneous power (in watts) is the power at any instant of time. It is the rate at which an element absorbs energy. Consider the general case of instantaneous power absorbed by an arbitrary combination of circuit elements under sinusoidal excitation, as shown in Figure.(1).

On many schematics the polarities of resistors are already assigned, so the directions of the currents should be assigned such that the current is entering the positive terminal. This will simplify later calculations.

WebFeb 16, 2015 · The reason for the passive reference convention is to keep track of how energy is flowing. If current is flowing from high to low potential then energy is being delivered to the device through which the current is flowing. If current is flowing from low potential to higher potential, then the device is delivering energy to the rest of the circuit. Web2.
