Question

In given LCR circuit, the voltage across the terminals of a resistance R and current through ammeter will bef (A) 200 V ; 5 A (B) 400 V ; 5 A (C) 4007, V ; 5 √2 A (D) 200 V ; 5 √2 A

Tardigrade Admin · Accepted Answer

V=√VR2+(VL-VC)2 ⇒ V=VR=200 V ⇒ I=(V/Z)=(V/√R2+(XL-XC)2) =(200/40)=5 A

Q. In given LCR circuit, the voltage across the terminals of a resistance R and current through ammeter will be $f$

$200 V; 5 A$

$400 V; 5 A$

$4007, V; 52 A$

$200 V; 52 A$

$V = V_{R}^{2} + (V_{L} - V_{C})^{2}$
$\Rightarrow V = V_{R} = 200 V$
$\Rightarrow I = \frac{V}{Z} = \frac{V}{R ^{2} + ( X _{L} - X _{C} ) ^{2}}$
$= \frac{200}{40} = 5 A$
