Answer #1

= here, a 100 Resists always has the same resistance. Because, the resistance doesn't depend upon the frequency.

- So, both in AC and DC circuits the resistance remains the same.

- But the 50 Capacita always doesn't has the same reactance. Beacuse, the capacits reasctance is depends upon the frequency of pthe AC circuit AC source. here, the rectance of the capacitor is

here, if frequency chnages then the reactance changes. For a very high frequency, the reactance decreases and for low frequency the reactance is increases.
