Question

IF THE CAPACITOR HAS PLATE AREA OF 0.2m² AND DISTANCE BETWEEN THEM IS 0.04 m. What is the capacitance if dielectric constant is E=0.001 C/VM.
please i need it hurry if correct mark u brainliest.please hurry.​

Answer 1

Answer:

The capacitance is 1.75 nF

Explanation:

From the question we are given that

   The inner radius is

    The outer radius is 000.1

   Length of the capacitor is L = 1m

   The dielectric constant is Di = 2

  The dielectric constant is  Di2 = 4

Generally the capacitance of a capacitor can be mathematically represented as

1.75nF

               

                 

                 

                 

                 

               

                 

Answer 2

$\\ \rm\Rrightarrow C=\dfrac{\epsilon_oA}{d}$

$\\ \rm\Rrightarrow C=\dfrac{0.2(0.001)}{0.04}$

$\\ \rm\Rrightarrow C=\dfrac{0.0002}{0.04}$

$\\ \rm\Rrightarrow C=0.005F$

$\\ \rm\Rrightarrow C=5mF$
