LR Charge Time Calculator

Brief for LR Charge Time Calculator:

Compute the L (inductor), R (resistor) or t (time) for a inductor and resistor in series, powered by a DC voltage.

Fill two of the three fields to compute the desired value, the inductance, the resistance or the time.

Brief for LR Charge Time Circuit:

The LR Charge Time Circuit consists of an inductor and resistor in series powered by a DC volatge, when time is 0 seconds (trun on the switch), it starts charging until it reach ~99% of the supply voltage (τ5), at that time maximum current (acounting with resistance) is passing through the circuit.

$RC Charge Time formula$

τ	Time in seconds, ~63% of charge
t5	Time in seconds, ~99% of charge
R	Resistance in Ohm
L	Inductance in Henry

τ5	s
R	Ω
L	H
τ0.5	~39% Charge
τ0.7	~50% Charge
τ1.0	~63% Charge
τ2.0	~86% Charge
τ3.0	~95% Charge
τ4.0	~98% Charge
τ5.0	~99% Charge

e+15 = Peta; e+12 = Tera; e+9 = Giga; e+6 = Mega; e+3 = Kilo; e-3 = mili; e-6 = micro; e-9 = nano; e-12 = pico; e-15 = femto
