A circuit consists of an inductor and two capacitors all in series. The inductor has a resistance of 10Ω and an inductance of 159μH. The first capacitor has 200pF and the second is a variable capacitor with a wide capacitive range. This series circuit is connected to a 50mV sinusoidal supply of fixed frequency 1MHz. (i) What value of the variable capacitance will be required for a resonance condition  (give the answer in pF)?

An alternating current E(t)=120sin(12t) has been running through a simple circuit for a long time. The circuit has an inductance of L= 0.44 henrys, a resistor of R=7 ohms, and a capacitor of capacitance C= 0.032 farads.What is the amplitude of the current I?
