= 1/2 x 3.14 x 1000x4.7 x 10-6.
= 1/2 x 3.14 x 1 x 4.7 1 0-3.
= 1000/2 x 3.14 x 1 x 4.7.
= 1000/29.516.
= 34 ohms.
= 1/2 x 3.14 x 1 x 4.7 1 0-3.
= 1000/2 x 3.14 x 1 x 4.7.
= 1000/29.516.
= 34 ohms.

Xc = 1/(2 * 3.14 * f * c).
= 1/(2 * 3.14 * 1000 * 0.0000047).
= 33.86.
= 1/(2 * 3.14 * 1000 * 0.0000047).
= 33.86.

@Prashanth Kotian.
How 4.7 x 10-6 becomes 4.7 x 10-3?

= 1/2x3.14x1000x4.7x10-6.
= 1/2x3.14x1x4.7x10-3.
= 1000/2x3.14x1x4.7.
= 1000/29.516.
= 34 ohms.
= 1/2x3.14x1x4.7x10-3.
= 1000/2x3.14x1x4.7.
= 1000/29.516.
= 34 ohms.

Xc=1/Jwc
=1/2*pi*f*c
=1/2*pi*f*c

Xc=jwc
as w=2*pi*f*c
Keeping factor aside
Xc=1/2*pi*f*c
by putting the values we have
=1/2*3.14*1000*4.7u
=34 ohms
as w=2*pi*f*c
Keeping factor aside
Xc=1/2*pi*f*c
by putting the values we have
=1/2*3.14*1000*4.7u
=34 ohms

Keeping factor aside. As we interested mainly on reactance .
So substituting in above relation.. We will get
1/2*3.12*1k*4.7micro =34 ohm
=1/2*pi*f*c
