X and Y are two circuits having coefficient of mutual inductance 3 mH and resistances \(10 \Omega\) and \(4 \Omega\) respectively. To have induced current \(60 \times 10^{-4} \mathrm{~A}\) in circuit Y , the amount of current to be changed in circuit X in 0.02 sec is
- A 1.6 A
- B 0.16 A
- C 0.32 A
- D 3.2 A
Answer & Solution
Correct Answer
(B) 0.16 A
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \text { } \mathrm{M}=3 \mathrm{mH}=3 \times 10^{-3} \mathrm{H}, \mathrm{R}_1=10 \Omega, \mathrm{R}_2=4 \Omega \text {, } \\ & \mathrm{I}_2=60 \times 10^{-4} \mathrm{~A}, \Delta \mathrm{t}=0.02 \end{aligned}\) \(\therefore \quad\) Induced current in Y is…
