In order to do DC circuit analysis, you need to develop a sign convention when assigning polarities or current direction for each element in the circuit. Under the passive convention, the positive voltage reference mark is associated with the current reference arrow. Here, the device power is positive when it absorbs power and is negative [...] . . . → Read More: DC Circuit Analysis: The Passive Sign Convention (Part 1) Here is an example illustraing the concepts of current, voltage and power: . . . → Read More: Electric Circuit Analysis – Circuit Variabes: Current, Voltage, Power (Examples) We are now getting to the key important circuit variables in analyzing the circuit. Namely, current voltage and power: . . . → Read More: Electric Circuit Variables: Current, Voltage and Power Here’s a recorded screen video about using animation to explain visually the meaning of voltage and current using a water pump analogy. The flash animation is by Professor Harrison from the University of Toronto. . . . → Read More: Electric Circuit Analysis – Water Analogy |
