I need help finding the Capacitance of capacitor A

following table. Insert units where appropriate and include uncertainties. y Applied voltage, V ( Charge, Q( I V 13 x 10-8 2v 26 x 10 - 8 3 v 39 x 10- 8 4 v 51 x 10- 8 6 V 7 7 X 108 8 V 0.96 x 10 - 6 Draw a graph Q vs V on graph paper then attach it to this proforma. The capacitance of capacitor A is: CA = +
