Question

Hello guys ;



Answer the attachment ;​

Answer 1

Explanation:

UNDERSTANDING THE CONCEPT:-

According to the question,

A)=>To draw maximum current from a series of LCR circuit, The circuit must be at resonance.

=> So, For resonance, we know at particular frequency,

Xl = Xc.

=>After this, We can find the maximum current by using teb respective formula.

B)We need to use the respective Formula to calculate the current.

CONCEPT REFRESHER:-

A) Formula

$\sf{v = \dfrac{1}{2\pi \sqrt{lc} } }$

B) Formula

$\sf{ I{}^{0} = \dfrac{e}{r} }$

$\huge\tt\fbox\purple{Answer}$

Let's Do It!!

$\sf{v = \dfrac{1}{2 \times 3.14 \times \sqrt{8 \times 2 \times 10 {}^{ - 6} } } }$

V = 39.80Hz

This frequency is known as the series resonance frequency.
