Supercsapacitor - Time to deliver a Constant Current

A supercapacitor (SC) (sometimes ultracapacitor, formerly electric double-layer capacitor (EDLC)) is a high-capacity ... more

Voltage gain - simplified formula (for equal impedances)

The power gain can be calculated using voltage instead of power using Joule’s first law to calculate a voltage gain. In many cases, the input and ... more

Output Voltage (voltage divider)

A voltage divider (potential divider) is a linear circuit that produces an output voltage that is a fraction of its input voltage. Voltage division refers ... more

Capacitive divider (only for AC)

A voltage divider (potential divider) is a linear circuit that produces an output voltage that is a fraction of its input voltage. Voltage division refers ... more

Electric Motor's efficiency

The electric motor’s efficiency is the mechanical output power divided by the electrical input power

Aharonov–Bohm effect - electric effect

The Aharonov–Bohm effect, sometimes called the Ehrenberg–Siday–Aharonov–Bohm effect, is a quantum mechanical phenomenon in which an electrically charged ... more

Impulse (Velocity)

Impulse is the product of a force and the time, for which it acts. The impulse of a force acting for a given time interval is equal to the change in linear ... more

Mechanical Advantage - Law of Lever

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. Ideally, the device preserves ... more

Current gain (for equal impedances)

The current gain can be calculated using current instead of power using Joule’s first law to calculate. In many cases, the input and output ... more

Uniform Circular Motion position (Y - coordinate)

In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with ... more
