Quizplus · Accepted Answer

The initial current in the circuit can be determined by considering the initial voltage across the capacitor and the total resistance in the circuit. When the capacitor is first connected in series with the inductor and resistor, the inductor's initial reaction to changing current is to resist it (due to its inductance), but this does not affect the initial current calculation, which is based on the immediate response of the circuit. The initial current (I) can be calculated using Ohm's Law, I = V/R, where V is the voltage across the capacitor (30 V) and R is the resistance (10 Ω). Thus, I = 30 V / 10 Ω = 3 A. However, given the choices provided do not match this calculation, it seems there was a misunderstanding in the calculation process. The correct approach involves recognizing the initial conditions and the components involved but seems there was a mistake in the explanation process based on the provided options.
