Question

Question 1:An amateur radio operator wishes to build a receiver that can tune a range from 13.6 MHzMHz to 15.5 MHzMHz . A variable capacitor has a minimum capacitance of 85 pFpF .

Part A; What is the required value of the constant inductance?

Part B:What is the maximum capacitance used on the variable capacitor?

Question 2: Calculate the displacement current IDID between the square plates, 8.2 cmcm on a side, of a capacitor if the electric field is changing at a rate of 1.4×1061.4×106 V/m⋅sV/m⋅s.
