标题: IEC 61058-1 table 18中的疑问
Table 18 – Test loads for electrical endurance tests for d.c. circuits
L/R < 1,15 ms
问题：L/R是什么意思？
9 P! K! L$ \. R% r" R+ {8 V+ I- h

L = inductance in H$ J* _3 E# w( }
R = resistance in Ohm, x# p9 _. z9 m! c$ _
! |' z5 h G7 J _5 C l, r
Time constant for L-R circuit is equal to L divided by R
