What happened to Norton AntiVirus Basic? Since we have a dependent source here, we will use a current source in evaluating the Equivalent resistance, i. Additional Information. Determine the values of R th and I sc that cause the given circuit to be the Norton equivalent circuit.
Calculating R TH: Keep independent voltage source as short-circuit as shown:. Consider the resistive circuit shown below, the value of Norton current across the terminal AB is. Any linear bilateral circuit containing the voltage in series can be converted into the current source with the parallel resistance. Then the equivalent circuit is shown below:. Any two terminal bilateral linear DC circuits can be replaced by an equivalent circuit consisting of a current source and a parallel resistor.
To find V oc : Calculate the open-circuit voltage across load terminals. To find I sc : Short the load terminals and then calculate the current flowing through it. This current is called Norton current or short circuit current I sc.
