Detailed Solution
Download Solution PDFThe correct answer is option 3): (10 A current source and a 2 S conductance)
Concept:
- Two electrical networks are said to be dual networks if the mesh equations of one network are equal to the node equation of the other
- Identical behaviour patterns observed between voltages and currents in two circuits illustrate the principle of duality.
- The dual networks are based on Kirchhoff Current Law and Kirchhoff Voltage Law.
- Some important dual relations are given below.
| Element | Dual element |
| Resistance | Conductance |
| Inductance | Capacitance |
| Series branch | Parallel branch |
| Mesh | Node |
| Switch closed | Switch open |
| Charge | Flux linkage |
| Voltage source | Current source |
| Link | Twig |
| π network | T network |
Calculation:
In an electric circuit, a 10 V voltage source is connected in series with a 2 Ω resistance. the dual of this circuit consists of 10 A current source and a 2 S conductance
