What is the maximum energy EmaxEmaxE_max stored in the capacitor at any time during the current oscillations

Answer 1

Complete Question

An L-C circuit has an inductance of 0.350 H and a capacitance of  0.290 nF . During the current oscillations, the maximum current in the inductor is 2.00 A .

What is the maximum energy $E_{max}$ stored in the capacitor at any time during the current oscillations?

Express your answer in joules.

Answer:

The value is   $E_{max} = 0.7 J$

Explanation:

From the question we are told that

   The inductance is $L = 0.350 \ H$

    The capacitance is $C = 0.290 \ nF = 0.290 *10^{-9 } \ F$

   The current is  $I = 2 \ A$

Generally the maximum energy is mathematically represented as

        $E_{max} = \frac{1}{2} * L * I^2$

=>       $E_{max} = \frac{1}{2} * 0.350 * 2^2$

=>     $E_{max} = 0.7 J$
