Question

The inertia for electric circuit is (symbols have their usual meanings)

• A. $L$
• B. $\frac{1}{L}$
• C. $C$
• D. $\frac{1}{C}$

Answer 1

Answer: (A)

$E=\frac{1}{2}k{x}^2+\frac{1}{2}m{v}^2\left(formechanicalsystem\right)$
$U=1q+\frac{1}{2}L{i}^2$ (for electrical system)
Hence L is called as inertia of electrical circuit.
