Which of the followings is/are active element?Answer areaVoltage sourceCurrent sourceBothNone of these.

Active Elements in Electrical Circuits

1. Definitions of Active Elements: Active elements in electrical circuits are components that can deliver energy to the circuit. The two primary types of active elements are voltage sources and current sources.

2. Analysis of Options:

   • Voltage Source: This is an active component that provides a constant voltage to the circuit, allowing current to flow. Examples include batteries and power supplies.
   • Current Source: This is another active component that provides a constant current to the circuit, regardless of the voltage across it. An ideal current source delivers a specific amount of current consistently.
   • Both: Since both voltage sources and current sources are considered active elements, this option could also be correct.
   • None of these: This option implies that there are no active elements, which is incorrect given the presence of voltage and current sources.

Conclusion

Based on the definitions and analysis, the correct answer is that both voltage sources and current sources are active elements.

Final Answer

Both voltage sources and current sources are active elements.
