5 Questions
How should the polarities of passive elements (resistors and other loads) be assigned?
Current always flows into the positive terminal
What is the first step in the circuit analysis process?
Choose an arbitrary direction of current flow
When is the power dissipated by an element considered positive?
When the current flows into the positive terminal
What is the power dissipated by the battery in the given example?
-1.2 W
In circuit analysis, what does it mean if the arbitrarily chosen direction of the current is consistent with the true polarity of the voltage source?
The source voltage will be a positive quantity
