The coefficient of mutual inductance, when magnetic flux changes by 2 × 1 0 − 2 Wb and current changes by 0.01 A is

Change in magnetic flux ( ϕ ) = 2 × 1 0 − 2 Wb and change in current ( I ) = 0.01 A . Change in magnetic flux, ϕ = 2 × 1 0 − 2 = M I = M × 0.01 or M = 0.01 2 × 1 0 − 2 = 2 H (where M = coefficient of mutual inductance).

The coefficient of mutual inductance, when magnetic flux changes by $2 \times 1 0^{- 2} Wb$ and current changes by $0.01 A$ is

Options:

Answer:

Solution:

Change in magnetic flux $(ϕ) = 2 \times 1 0^{- 2} Wb$ and change in current $(I) = 0.01 A$ . Change in magnetic flux, $ϕ = 2 \times 1 0^{- 2} = M I$ $= M \times 0.01 or M = \frac{2 \times 1 0 ^{- 2}}{0.01} = 2 H$ (where $M =$ coefficient of mutual inductance).
