The basic circuit elements in an alternating current (AC) circuit which store energy in an electric and magnetic field areI. resistorII. inductorIII. capacitorIV. transistor
Correct answer: C. II and III
- A. I and II
- B. I and IV
- C. II and III
- D. III and IV
Explanation
The correct answer is Option C: II and III. In alternating current (AC) circuits, inductors store energy in magnetic fields, and capacitors store energy in electric fields. Resistors dissipate energy as heat, and transistors, while useful for switching and amplification, do not store energy in electric or magnetic fields. Therefore, Options A, B, and D are incorrect.

About AC Through Resistor, Capacitor and Inductor
Alternating current through a resistor, capacitor and inductor involves phase relationships between voltage and current, reactance, impedance and energy transfer. A resistor keeps voltage and current in phase, while a capacitor and inductor produce opposite phase shifts, a distinction used in circuit diagrams and numerical calculations.
