Answer:
b. Passive reference configuration implies that the reference direction of the current is the same direction as the reference direction of the voltage.
Explanation:
Term Passive reference configuration implies that current i flowing through the element voltage across which is v.
P= v×i
we say that power is absorbed or released by an element depends upon the sign of P. And This depends upon the sign of current entering and the voltage across the terminal. This is know as passive reference configuration.
If the current enters the negative end of polarity the power P= -v×i
therefore here option B is the correct answer.
