What is the capacitance of a capacitor?
The capacitance of the capacitor is 0.12 F and it is charged to a pd of 9.0 V. The weight of the mass raised is 3.5 N. Calculate the maximum height to which the mass could be raised. Give your answer to an appropriate number of significant figures. Give two reasons why the value you have calculated in part (i) would not be achieved in practice.
How are capacitor X and Y separated?
The plates of both capacitor X and capacitor Y are separated by a vacuum. Complete Table 1.1 for this circuit. Table 1.1 How did you do? The total capacitance for two capacitors and connected in parallel is given by the equation: Using the equation given, calculate the total capacitance of the circuit shown in Fig. 1.1 in Farads, F. How did you do?
Why does a capacitor charge exponentially?
As seen in the current-time graph, as the capacitor charges, the current decreases exponentially until it reaches zero. This is due to the forces acting within the capacitor increasing over time until they prevent electron flow. The potential difference needs to increase over time exponentially as does charge.
