SUMMARY
The initial current (j(0)) in a voltage-driven series LCR circuit is definitively 0 when the switch is first closed, regardless of the type of voltage source used. The derivative of the current at time zero, j'(0), is equal to V(0)/L, where V(t) represents the source voltage and L is the inductance. This conclusion is supported by fundamental circuit theory principles governing LCR circuits.
