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`

Step-by-step 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) =  (1)/(2)  *  L  *  I^2`

=>
`E_(max) =  (1)/(2)  *   0.350  *  2^2`

=>
`E_(max) =   0.7 J`
