The voltage is regular.

Q5. State Thevenin Theorem?

This theorem states that any linear community with output terminal AB can be replaced through a single voltage source V in collection with a single impedance.

Q6. Define Cut-off Frequency?

The frequency that separates the skip and attenuation band is known as reduce-off frequency.

Q7. What Are The Properties Of A Resistor?

The residences are high resistivity, resistance to oxidation, corrosion and moisture.

Q8. List The Characteristics Of Filter?

An ideal filter would trmit signals below the skip-band frequencies without attenuation and completely suppress the sign with attenuation band of frequencies with a pointy cut-off profile.

Q9. State Superposition Theorem?

If some of voltages or current sources are acting simultaneously in a linear network the resultant present day in any branch is the algebraic sum of cutting-edge that might be produced in it when each supply acts alone changing all other impartial assets by means of their internal resistances.

Q10. Which Capacitor Is Preferred For High Voltage And Frequency?

The vacuum and gasoline filled capacitor are used for high voltage and frequency programs.

Q11. Define Active Filter?

The active filter out incorporates components like operational amplifier that introduce a few gain in the sign.

Q12. What Is The Material Used For Inductance Coil?

The fabric used is marble due to the fact it's miles unaffected by using atmospheric situations.

Q13. Define Norton Equivalent Circuit?

The Norton equal circuit is a modern generator that is located in parallel to internal resistance.

Q14. Is The Theorem Applicable To A.C. Sources?

No, it's far applicable to dc circuits with and without managed assets.

Q15. What Is The Efficiency During Maximum Power Trfer?

Efficiency during maximum energy trfer 50%.

Q16. Define Filter?

A filter is an electrical network which can trmit signals within a exact frequency variety.

Q17. List The Disadvantages Of Constant K Filters?

The attenuation does not boom hastily past cut-off frequency. Characteristics impedance varies widely inside the skip band from favored fee.

Q18. Define Unilateral Circuit?

The circuit whose houses are not same in either route is called unilateral circuit.

Q19. List Advantages Of Active Filter Over Passive Filter?

Active filter out do away with cumbersome components. It gives gain. It can power low impedance hundreds. It is easy to tune

Q20. List Examples Of Voltage Source?

The examples of voltage supply are battery and generator.

Q21. What Are The Applications Of Filter?

The Filter is utilized in voice frequency telegraphy, multi channel communique, TV broadcasting and telephony.

Q22. What Is Q Factor?

The Q issue is ratio of inductive reactance to resistance of a coil.

Q23. What Is Inductance?

It is the assets of a cloth via virtue of which it opposes any trade of value and path of current passing via the conductor.

Q24. What Is Resistance?

The resistance is the property of a material to oppose the waft of contemporary in a cloth. Its unit is ohm.

Q25. What Is The Unit Of Charge And Current?

The devices are coulomb and ampere.

Q26. How Equivalent Impedance Is Calculated In Thevenin Theorem?

All unbiased voltage assets are short circuited and all impartial modern-day resources are open circuited.

Q27. State Maximum Power Trfer Theorem?

A resistance load being linked to a dc network gets maximum power while load resistance is same to inner resistance.

Q28. What Happens To Voltage When Current Through The Inductor Is Constant?

The voltage throughout inductor is 0.

Q29. What Are Dependent Sources?

When power of voltage or modern-day modifications inside the supply for any change in the related community they may be known as based resources.

Q30. What Is The Unit Of Attenuation?

The unit is decibel and neper.

Q31. Define Characteristics Impedance?

The traits impedance of a filter fits with circuit to which it's miles linked at some stage in the skip band.

Q32. When We Use 3-terminal Resistor?

It is used while resistance is much less than 1 ohm.
