CAPACITORS Theoretical Problems ) You will be charging your capacitors (or combinations of capacitors) using a constant current source; it will generate a voltage vs time graph that is a straight line, like below: V 1) What is the relationship between the gradient of this graph, the current, and the capacitance of the capacitor being measured? - 7 L r 2) Use your above equation to derive an expression for the uncertainty in the capacitance, as a function of the uncertainty in the gradient and the uncertainty in the current. 7 L - - - J
