1 Independent Current Sources An independent current source is an energy source that pushes a constant flo w of electrons through an electrical circuit regardless of the load presented to it. In other words, a 1 amp source will main- tain a current flow of 1 amp through its terminals if it has an open circuit or short circuit as a load. The symbol for the current source and its V-I curve is shown below. The current source symbol must be identified with at least its direction of current flow marked and a value or variable for its current.

Unformatted text preview: Another way to think of a current source is of a constant speed motor driving a water pump. The constant speed motor will always deliver a constant volume of water per unit time through the pump. This is analogous to a constant flow of electrons per unit time. 1A I V independent current source The independent current source will rise or fall to whatever voltage necessary to maintain a constant current flow. 0.5 1.0 1.5 I1 current magnitude reference designator constant speed motor water pump I1 current source...
