Answer» The correct option is (d) The dependent voltage source is short-circuited keeping the independent voltage source untouched and the dependent current source is open-circuited keeping the independent current source untouched Best explanation: While computing the Norton EQUIVALENT voltage consisting of both dependent and independent sources, we FIRST find the equivalent RESISTANCE called the Norton resistance by OPENING the two terminals. Then while computing the Norton current, we short-circuit the dependent voltage sources keeping the independent voltage sources untouched and open-circuiting the dependent current sources keeping the independent current sources untouched.
