Time Constant in DC Circuit Inductors
An inductor is, therefore, characterized by its time constant (τ = tau), which is determined using the formula: τ = L R τ = L R. where. τ = time constant in seconds. L = inductance in henrys. R = resistance in ohms. This expression shows that a greater inductance and a lower resistance will cause a longer time constant.

How to read battery discharge curves
Terminal Voltage (Vt) is the voltage between the battery terminals when a load is applied; this is typically lower than Voc. Cut-off Voltage (Vco) is the voltage at which the battery is specified to be fully discharged. While there is usually charge remaining, operation at voltages lower than Vco can damage the battery.
