6 FAQs about [The capacity of a capacitor decays over time]

What is the decay of charge in a capacitor?

The decay of charge in a capacitor is similar to the decay of a radioactive nuclide. It is exponential decay. If we discharge a capacitor, we find that the charge decreases by half every fixed time interval - just like the radionuclides activity halves every half life.

Do capacitors decay exponentially?

The voltage, current, and charge all decay exponentially during the capacitor discharge. We can charge up the capacitor and then flip the switch and record the voltage and current readings at regular time intervals and plot the data, which gives us the exponential graphs below. The half life of the decay is independent of the starting voltage.

How does capacitance affect a capacitor?

A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%). The two factors which affect the rate at which charge flows are resistance and capacitance.

What are the discharge curves of a capacitor?

The discharge curves of a capacitor are exponential decay curves. The voltage vs time, charge vs time, and current vs time graphs are all exponential decays, reflecting the continual decrease of these quantities as the capacitor discharges. At time t = τ, the voltage, charge, and current have reached about 37% of their initial values.

What factors affect the rate of charge on a capacitor?

The other factor which affects the rate of charge is the capacitance of the capacitor. A higher capacitance means that more charge can be stored, it will take longer for all this charge to flow to the capacitor. The time constant is the time it takes for the charge on a capacitor to decrease to (about 37%).

Do capacitors lose charge over time?

Capacitors will lose their charge over time, and especially aluminium electrolyts do have some leakage. Even a low-leakage type, like this one will lose 1V in just 20s (1000 μ μ F/25V). Nevertheless, YMMV, and you will see capacitors which can hold their charge for several months. It's wise to discharge them.
