Question

Which equivalence correctly states the value of \[1\ \mathrm{H}\] ?

Options

• \[1\ \mathrm{H}=1\ \mathrm{V\cdot s/A}=1\ \mathrm{Wb/A}\]

• \[1\ \mathrm{H}=1\ \mathrm{V/A}=1\ \mathrm{Wb\cdot A}\]

• \[1\ \mathrm{H}=1\ \mathrm{A/(V\cdot s)}=1\ \mathrm{A/Wb}\]

• \[1\ \mathrm{H}=1\ \mathrm{V\cdot A/s}=1\ \mathrm{Wb/A}\]

Answer 1

A Henry is a volt-second per ampere, consistent with induced EMF per rate of change of current. It is also a Weber per ampere, consistent with flux linkage per current.
