6 FAQs about [Capacitor Knowledge Points Discharge and Charge]

What are the graphs associated with capacitor charge and discharge?

The interpretation of the graphs associated with capacitor charge and discharge is pivotal in understanding the concepts of capacitance. The gradient of the Q vs. Time graph at any point gives the instantaneous current in the circuit. The area under the V vs. Time graph represents the total energy stored in the capacitor.

What is the graphical representation of capacitor charging and discharging?

Understanding the graphical representation of capacitor charging and discharging is crucial for comprehending the underlying physics. The voltage across the capacitor increases logarithmically over time as it charges. The charge on the capacitor, represented by Q, follows a similar pattern, increasing as the capacitor stores more energy.

How do you calculate the discharge of a capacitor?

An excellent AQA A-level Physics student would approach this question by applying the formula for the discharge of a capacitor, V = V0 e(-t/RC), where V0 is the initial voltage, V is the voltage at time t, R is the resistance, and C is the capacitance. Given that the voltage halves in 2 minutes, V0 = 12 V and V = 6 V.

How is energy dissipated in charging a capacitor?

How does a capacitor store charge?

Consider a circuit having a capacitance C and a resistance R which are joined in series with a battery of emf ε through a Morse key K, as shown in the figure. When the key is pressed, the capacitor begins to store charge. If at any time during charging, I is the current through the circuit and Q is the charge on the capacitor, then

What happens when a capacitor reaches 0?

This will gradually decrease until reaching 0, when the current reaches zero, the capacitor is fully discharged as there is no charge stored across it. The rate of decrease of the potential difference and the charge will again be proportional to the value of the current. This time all of the graphs will have the same shape:
