If the input voltage V_ i to the circuit below is given by V_ i (t)=A (2 f t) , the output voltage is given by V _ o ( t )= B (2 ft + ) Which one of the following four graphs best depict the variation of vs f ?

Step-by-step solution

Resultant of V_ C , V_ R & B give V_ i and angle between V_ i & B is . When f is very high X_ C O then V _ C O Resultant of V _ C , V _ R & ~B lie between B and V _ R B lag behind At higher frequency become - ve.
