Time constant of a capacitive circuit increases with the ?

 

Q. कैपेसिटिव सर्किट का समय स्थिरांक किसके साथ बढ़ता है?

A)धारिता में वृद्धि और प्रतिरोध में कमी [increase of capacitance and decrease of resistance]
B)धारिता में वृद्धि और प्रतिरोध में वृद्धि [increase of capacitance and increase of resistance]
C)धारिता में कमी और प्रतिरोध में कमी [decrease of capacitance and decrease of resistance]
D)धारिता में कमी तथा प्रतिरोध में वृद्धि [decrease of capacitance and increase of resistance]
 

Answer: B)धारिता में वृद्धि और प्रतिरोध में वृद्धि [increase of capacitance and increase of resistance]

 

Explanation :- 

i) The time constant of a capacitive circuit - The time constant is the time it takes for the circuit to reach 68% of its final value. The formula for the time constant is τ = RC. hence Resistance and capacitance increase then constant also increase. कैपेसिटिव सर्किट का समय स्थिरांक - समय स्थिरांक वह समय है जो सर्किट को अपने अंतिम मूल्य के 68% तक पहुंचने में लगता है। समय स्थिरांक का सूत्र τ = RC है। इसलिए प्रतिरोध और धारिता बढ़ती है तो स्थिरांक भी बढ़ता है।

 

ii) The time constant of an inductive circuit, also known as an RL circuit, is calculated using the formula (τ =L/R),  hence Resistance decrease and inductance increase then constant also increase.

where: τ  The time constant, measured in seconds 
L The inductance of the circuit, measured in Henries
R: The resistance of the circuit, measured in ohms        
The time constant is a key concept in electrical engineering that measures how quickly a system responds to a step input. It represents the time it takes for the circuit to reach 63.2% of its final value.
