Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
- In a purely resistive circuit, voltage and current are in the same phase i.e. angle between current and voltage is 0°.
- In a purely inductive circuit, current lags behind voltage by an angle 90° i.e. angle between current and voltage is - 90°.
- In a purely capacitive circuit, current leads the voltage by an angle 90° i.e. angle between current and voltage is + 90°.
Application:
The voltage applied to a pure capacitor = V sin(4t)
Now current through the pure capacitor is
Where A is the peak value of current
