An electrical circuit having combinations of resistances and capacitance is given below. The current, flowing through the circuit will be
- A. 1 A
- B. 2 A
- C. 1.5 A
- D. 0.5 A ✓
Correct Answer: D. 0.5 A
Explanation
In a steady-state DC circuit, a capacitor acts as an open circuit (blocking current). Therefore, current only flows through the resistors connected in series with the voltage source. With a 10 V source and two 10 \Omega resistors in series (20 \Omega total effective resistance), the current is I = \frac{V}{R} = \frac{10}{20} = 0.5 \text{ A}.
