Question

In the following circuit the emf of source is E°=200V ,R=20ohm L is 0.1 H ,C is 10.6 F and frequency is variable then

Answer 1

Answer:

According to the problem it is given that emf is 200V the resistance is 20ohm and the length is 0.1 H the Current is given as 10.6F

Now we know that Xc = 1/wc = [ where Xl = wl]

Therefore when frequency f is zero current is also zero, and when the frequency is at infinity the current will be zero again.
