Calculation of Current in the Coil

To determine the current in the coil, we can use the formula for the energy stored in an inductor:

Energy (E) = (1/2) * L * I^2

where: - E is the energy stored in the inductor (given as 0.19 J) - L is the inductance of the coil (given as 95 mH or 0.095 H) - I is the current flowing through the coil (to be determined)

Rearranging the formula, we can solve for the current (I):

I = sqrt(2 * E / L)

Substituting the given values, we have:

I = sqrt(2 * 0.19 J / 0.095 H)

Calculating this expression, we find that the current flowing through the coil is approximately 0.618 A.

Please note that this calculation assumes ideal conditions and does not take into account any resistance or other factors that may affect the actual current in the coil.
