NEET PHYSICSEasy

In SI, Henry is the unit of:

Self inductance

Mutual inductance

(1) and (2) both

None of the above

Definition: The Henry (symbol: H) is the SI derived unit of inductance.
Application: It is used as the unit for both Self-inductance ( $L$ ) and Mutual inductance ( $M$ ).
Source Verification: According to the NCERT Physics text, the constant of proportionality $L$ (self-inductance) has the SI unit of henry . Similarly, the coefficient $M$ (mutual inductance) corresponds to the same physical dimension (flux linkage per ampere) and is also measured in henry .
Dimensional Analysis: Both quantities define the relationship between induced emf and the rate of change of current ( $\varepsilon = -L \frac{dI}{dt}$ or $\varepsilon = -M \frac{dI}{dt}$ ), resulting in the same unit .
