An lc circuit has a capacitor with c = 0.2 uf and a solenoid with inductance l = 3 mh. initially the capacitor is fully charged and has a voltage across its plates of 2 v. the capacitor then begins to discharge. what is the magnitude of the current in the circuit when the voltage across the capacitor is 1 v?

The magnitude of the current in the circuit is 0.01159 A.

Explanation:

Given that,

Capacitor

Inductance

Voltage V = 2 V

We need to calculate the energy when the capacitor is charged

Using formula of energy

Put the value into the formula

When the capacitor is discharged

Using formula of energy

rms value of current,

Hence, The magnitude of the current in the circuit is 0.01159 A.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

its a 5.5 n
