Norton equivalent with current sources

Example: 6. Let us find the open circuit voltage v o. At node x, nodal analysis gives. Applying of KVL at left hand loop yields. Substitution of 1 in 2 yields. Next, short circuit is applied at x-y terminals such that v o becomes zero figure Example: 7. Let us first apply short circuit at x-y terminal figure At node 2 , KCL yields,.

Again at node 1 , nodal analysis gives. Let us now keep x-y open circuited such that potential at x-y terminal becomes v o.

At node 1 , nodal analysis gives. This gives Norton equivalent as. Example: 8. Let us now delete the right part of the given circuit and a 1A current sources is applied across x-y as shown in figure This is an equivalent circuit to calculating the Thevenin resistance.

The voltage at the terminals is calculated for a source of a 1 A. Take a look at the current on the terminals. This voltage divided via the 1 A current is the Norton impedance R no. Based on the type of sources that can be present in the network. If short-out the two voltage sources and open circuit terminals A and B, the two resistors are now effectively connected together in parallel.

The value of the inner resistor R s is found by calculating the total load resistance on terminals A and B giving us the following circuit:. Again, the 2 resistors are connected in parallel across terminals A and B which gives us a total resistance of:. The voltage across the terminals A and B with the load resistor connected is given as:.

Remember that this theorem applies to both AC and DC regions. It works in AC circuits for impedance and resistance statistics.
