Start and Run Capacitors for Electric Motors

Run Capacitor. A run capacitor (figure 9) is used in single-phase motors to maintain a running torque on an auxiliary coil while the motor is loaded. These capacitors are considered continuous duty while the motor is powered and will remain in the circuit while the start capacitor drops out. Not all single-phase motors have run capacitors.

4.8: Energy Stored in a Capacitor

Knowing that the energy stored in a capacitor is UC = Q2 / (2C), we can now find the energy density uE stored in a vacuum between the plates of a charged parallel-plate capacitor. We just have to divide UC by the volume Ad of space between its plates and take into account that for a parallel-plate capacitor, we have E = σ / ϵ0 and C = ϵ0A / d.

How Capacitors Work | HowStuffWorks

Inside the battery, chemical reactions produce electrons on one terminal and the other terminal absorbs them when you create a circuit. A capacitor is much simpler than a battery, as it can''t produce new electrons — it only stores them. A capacitor is so-called because it has the "capacity" to store energy.
