In a R-C series circuit, current_applied voltage by θ=
Correct answer: C. C
- A. A
- B. B
- C. C
- D. D
Explanation
In a pure capacitive circuit, the current leads the voltage by 90°In series RC circuit, the current leads the voltage by an angle in between 0 to 90°In pure inductive circuit, the current lags the voltage by 90°In series RL circuit, the current lags the voltage by an angle in between 0 to 90°

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
