∴

C = 0.00035F

LAST Step Convert to Output's Unit

∴

C = 350μF

Capacitance using Time Constant Formula Elements

Variables

Capacitance

Capacitance is the capability of a material object or device to store electric charge. It is measured by the change in charge in response to a difference in electric potential.

Symbol: C

Measurement: CapacitanceUnit: μF

Note: Value can be positive or negative.

Formulas to find Capacitance

Time Constant

Time constant is the response representing the elapsed time required for the system response to decay to zero if the system had continued to decay at the initial rate.

Symbol: τ

Measurement: TimeUnit: ms

Note: Value should be greater than 0.

Formulas to find Time Constant

Resistance

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).

Symbol: R
