A series circuit contains a resistance R a capacitor CF a coil L H supplied by a 1 c source with e m f EV Derive an expression for the current in the circuit for critica lamping condition The initial current i 0 A and the capacitor voltage vc 0 V i If the source e m f 25 V coil inductance is 600 mH and the capacitor is 200 mF what is the voltage across the capacitor at t 1 0 s Hints 1 use KVL to write equation v VR VC E 2 make use of v Li VR Ri vc q C and i q to write differential equation in terms of q 3 remember for critical damping the C F y A Bt e because 0 4 the value of R can be found for critical damping condition from L and C
