A 12 V battery is connected across two parallel branches. The first branch contains a 4 resistor, while the second branch contains a 6 resistor in series with a 10 F capacitor. What is the steady-state current drawn from the battery?

Options

  1. A5 A
  2. B1.2 A
  3. C3 A
  4. D2 A

Correct answer

C. 3 A

Step-by-step solution

At steady state, the capacitor is fully charged and acts as an open circuit. Therefore, no current flows through the second branch containing the 6 resistor and the capacitor. The entire current from the battery flows only through the first branch containing the 4 resistor. Using Ohm's law, the steady-state current is: I = V R = 12 4 = 3 A Answer: 3 A
