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

Sagnac Effect - TIme Difference

The Sagnac effect (also called Sagnac interference), named after French physicist Georges Sagnac, is a phenomenon encountered in interferometry that is ... 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

Tortuosity - alternative method

Tortuosity is a property of curve being tortuous (twisted; having many turns). There have been several attempts to quantify this property. ... more
