A pair of adjacent coil has a mutual inductance of 1.5 H . If the current in one coil changes from 0 to 10 A in 0.5 s . What is the change of flux linkage with the other coil ?
- A 15 Wb
- B \(30 W b\)
- C 1.5 Wb
- D 0.15 Wb
Answer & Solution
Correct Answer
(A) 15 Wb
Step-by-step Solution
Detailed explanation
A
\(|\varepsilon|=\frac{\Delta \phi}{\Delta t}=M \frac{\Delta I}{\Delta t}\)
\(\begin{aligned} \therefore \quad \Delta \phi = M \Delta I \\ \Delta \phi =1.5 \times(10-0) \\ \Delta \phi =15 W b\end{aligned}\)
\(|\varepsilon|=\frac{\Delta \phi}{\Delta t}=M \frac{\Delta I}{\Delta t}\)
\(\begin{aligned} \therefore \quad \Delta \phi = M \Delta I \\ \Delta \phi =1.5 \times(10-0) \\ \Delta \phi =15 W b\end{aligned}\)
