Given Information:
Inductance = L = 20 mH
Capacitance = C = 0.200 µF
Current = I = 0.100 A
Required Information:
Potential difference = V = ?
Answer:
Potential difference = 31.62 V
Explanation:
The energy stored in the electric field is given by
Ue = ½CV²
The energy stored in the magnetic field is given by
Um = ½LI²
From the principle of conservation of energy,
Ue = Um
½CV² = ½LI²
CV² = LI²
V² = LI²/C
V = √LI²/C
V = √(20x10⁻³*0.100²)/0.200x10⁻⁶
V = 31.62 V
