Question
The SI unit of the inductance, the henry can by written as
Options
A.weber/ampere
B.volt-second/ampere
C.joule/(ampere)2
D.ohm-second
Solution
(a) L = 
or henry = 
(b) e = - L
∴ L = -
or henry =
(c) U =
Li2 ∴ L = 
or henry =
(d) U =Li2 = i2Rt
∴ L = Rt or henry = ohm - second
or henry = (b) e = - L
∴ L = -
or henry =
(c) U =
Li2 ∴ L = or henry =
(d) U =
Li2 = i2Rt∴ L = Rt or henry = ohm - second
