Examples for

Capacitors

Capacitors are circuit elements that store electrical energy in an electric field. Use Wolfram|Alpha to compute the capacitance of a parallel plate capacitor, capacitors in parallel and series, and a variety of other physical systems. Calculate the energy stored in a capacitor or its capacitive reactance.

Capacitors

Compute the capacitance of different physical systems.

Compute the capacitance of a parallel plate capacitor:

capacitance of parallel plates

Compute the capacitance for capacitors in series:

series capacitance 200uF, 500uF

Compute the stored energy of a capacitor:

capacitor energy 250mF, 1C

Compute capacitive reactance:

capacitive reactance 100uF, 60Hz

Determine the capacitance of physical systems:

capacitance of two parallel cylinders at 20 cm distance
concentric sphere capacitance with radius 3mm and 4mm
2mm radius disk's self capacitance
self capacitance of a solid cylinder
1cm ball's self capacitance
capacitance of two identical spheres touching with 2mm radius
