C = A ⋅ B ? ⋅ A ? ⋅ B ?

Using De-Morgan Theorem

C = A ⋅ B ? ⋅ A ? ⋅ B ?

C = B ( A + A ? ) ? = B ?

Therefore

Energy Stored in a Capacitor Class 12th

A capacitor is connected to a 20 V battery through a resistance of 10 Ω .  It is found that the potential difference across the capacitor rises to 2V in 1 μ s .  The capacitance of the capacitor is________   μ F .

Given  I n ( 1 0 9 ) = 0 . 1 0 5

V = 10 ( 1 − e − t / R C )  

2 = 20 ( 1 − e − t / R C )  

1 1 0 = 1 − e − t / R C

e t / R C = 1 0 9

t R C = l n ( 1 0 9 ) = 0 . 1 0 5

C = t R * 0 . 1 0 5 = 1 0 − 6 1 0 * 0 . 1 0 5 = 0 . 9 5 μ F
