The time required for the current flowing in the LR series circuit to reach its maximum steady state value is equivalent to about 5 time constants or 5Ï. This time constant Ï, is measured by Ï = L/R, in seconds, were R is the value of the resistor in ohms and L is the value of the inductor in Henries.
Chem Guide explains that by rearranging the equation, the units of the ideal gas constant R are L x atm / moles x K, and the value of R is 0.082057 L atm / (mol K). In other unit systems, especially SI, the units of R are Joules / (mol K), and its value is 8.314.
