3 points for answering how associated and non-associated directions are defined with examples, 5 points for correct answers.
1. For a circuit element, when the reference directions of its voltage and current are the same, it is generally referred to as an associated reference direction； 2. In the case of a related reference direction, if the component’s power is positive, it indicates that the component consumes power ； On the contrary, if the power of a component is negative, it indicates that the component is emitting power. 3. When the reference directions of the voltage and current of a circuit component are opposite to each other, this is usually referred to as non-associated reference directions. 4. In the case of non-associated reference directions, all of the above conclusions are reversed; that is, when the power of a component is positive, it indicates that the component is emitting power ； When the component power is negative, it indicates that the component consumes power.
When the reference directions of current and voltage are the same, it is a correlated direction; otherwise, it is an uncorrelated direction
When the actual direction is the same as the reference direction, the current (or voltage) value is positive, indicating a correlated direction. When the actual direction is opposite to the reference direction, the current (or voltage) value is negative, indicating a non-correlated direction.
When the reference directions of current and voltage are the same, it is a correlated direction; otherwise, it is an uncorrelated direction.
Regarding how to define associated and non-associated directions and providing examples: Answer: 1. For a circuit element, when the reference directions of its voltage and current are the same, it is usually referred to as an associated reference direction； 2. In the case of a related reference direction, if the component’s power is positive, it indicates that the component consumes power ； On the contrary, if the power of a component is negative, it indicates that the component is emitting power. 3. When the reference directions of the voltage and current of a circuit component are opposite to each other, this is usually referred to as non-associated reference directions. 4. In the case of non-associated reference directions, all of the above conclusions are reversed; that is, when the power of a component is positive, it indicates that the component is emitting power ； When the component power is negative, it indicates that the component consumes power.
