In a series R-C circuit the supply voltage (V ~s ) is kept constant at 2 V and the frequency f of the sinusoidal voltage is varied from 500 Hz to 2000 Hz . The voltage across the resistance R =1000 ohm is measured each time as V_ R . For the determination of the C a student wants to draw a linear graph and try to get C from the slope. Then she may draw a graph of
