A battery connected to a capacity 20 F is charged to a potential of 35 ~V . The battery is disconnected. A pure inductor coil of 200 mH is connected across the capacitor so that LC oscillations are set up.The maximum current in the coil is

Step-by-step solution

Capacitance, C =20 F Voltage applied to capacitor, V =35 volts Inductance connected to the capacitor, L =200 mH To find: The maximum current in the inducting coil. The charge stored in the capacitor is given by: Q ₀= CV The maximum current flowing in the series LC circuit is: I_ max =Q_ ow The frequency of a series LC circuit is given by: = 1 LC Substitute the values in equation of maximum current. aligned & I_ =( CV ) 1 LC = C L V & I _ = 20 10⁻⁶ 200 10⁻³ 35=0.35 ~A aligned
