Question

In an LC circuit the capacitor has maximum charge q0. The value of ${\left(\frac{dI}{dt}\right)}_{max}$ is

• A. $\frac{q_0}{LC}$
• B. $\frac{q_0}{\sqrt{LC}}$
• C. $\frac{q_0}{LC}-1$
• D. $\frac{q_0}{LC}+1$

Answer 1

The correct option is A $\frac{q_0}{LC}$

${\left(\frac{dI}{dt}\right)}_{max}$ than $\frac{q_0}{LC}$ is the maximum change in current
$I=I_{o}coswt$
$\left(\frac{dI}{dt}\right)=\frac{I_o}{w}$
