Unformatted text preview: ction of voltage can be obtained after solving the circuit. Similar to the double‐subscript notation for current, there is double‐subscript notation for voltage as well. Another way to show voltage across an element is to use an arrow, with the arrowhead being equivalent to the positive polarity of the voltage. Ideal Current Source An ideal independent current source forces a specified current to flow through itself, irrespective of the voltage across it. This means, no matter what element or elements are connected across it, the current source will supply the same current. 12 EE1002 Introduction to Circuits and Systems iL I S Is vL I S RL RL Fig. Ideal Current source Dependent current source A dependent current source force a specified current to flow from it, which depends on the voltage or current in another element in the circuit If the control element (x) is voltage in another branch, then it is a voltage‐controlled current source. If the control element is current in another branch, t...
