At what frequency would a capacitor of 2.5Î¼F used in radio circuit have a resistance of 250Î©

At what frequency would a capacitor of 2.5Î¼F
used in radio circuit have a resistance of 250Î©

Correct Answer: Option B

Explanation:
Capacitive Reactance = ___1

2Ï€ + C

=> 250 = ____1

2 x Ï€ x f x 2.5 x 10⁶

âˆ´ ²⁵⁰/₁ = ^10[sup]6[/sup]/_5.0xf=> F = ___10⁶

250 x 5.0 x Ï€

= 10⁶

1250Ï€

800/Ï€
