Question

The unit henry is equal to ______.

विकल्प

• Watt

• ohm-second

• dyne

• Wb/m²

Answer 1

The unit henry is equal to ohm-second.

Explanation:

The Henry (H) is the SI unit of inductance. It is defined as the inductance of a coil in which a current change of 1 ampere per second induces an EMF of 1 volt.

Mathematically, L = `(V × s)/A`

Now, since `V/A` = ohm

we get, L = ohm × second.

Hence, the unit of henry is equivalent to an ohm-second.
