Voltage gain

In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input ... more

Voltage gain (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

Current gain

In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input ... more

Power gain

In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input ... more

Rotary variable differential transformer(RVDT) - Rotor mechanical angle

A rotary variable differential transformer (RVDT) is a type of electrical transformer used for measuring angular ... more

Transistor regulator ( Rv providing a bias current)

In the simplest case a common collector transistor (emitter follower) is used with the base of the regulating transistor connected directly to the voltage ... more

Potentiometer Voltage Divider

Potentiometer is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider. The potentiometer can be used as a voltage ... 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

Current gain - simplified formula (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
