Question 297: Units , Dimensions and Error Analysis

Question

The SI unit of inductance, the henry can be written as

Accepted Answer

Induction $$L = {\phi  \over i} = $$ weber/Ampere
Also, $$e =  - L\left( {{{di} \over {dt}}} ight) \Rightarrow L = {{ - e} \over {(di/dt)}} = {{volt - {\mathop{m second}
olimits} } \over {Ampere}}$$
Also, $$U = {1 \over 2}L{i^2} \Rightarrow L = {{2U} \over {{i^2}}} = {{Joule} \over {{{(Ampere)}^2}}}$$
and $$U = {1 \over 2}L{i^2} = {i^2}RT \Rightarrow L = RT = $$ Ohm-second
