Question

please fast,For the following circuit when R₁ Rx=R₂ R₃ Which one is correct

A RI R3 + DE No B R2 ti R х C

Select one:

a.  Current throgh BD is zero and V_B=V_D

b.  V_A=V_C

c. Current through AC is Zero

d. V_G=0 and V_A=V_C

e. Current through AC is one

Answer 1

SOLUTION:

ANSWER: a) current through BD is zero , V​​​​​​B = V​​​​​​D

CALCULATION:

Their

$R_{1}.R_{x}=R_{2}.R_{3}$

R1 R3 R2 R.

This condition are follow the wheatstone bridge principal.

According to wheatstone bridge principal there potential different or voltage at position of B and D are same

So $V_{B}=V_{D}$

That is clear the $V_{B}=V_{D}$ so no potential different between B and D points so their is no follow the any current

Then we can say that, I​​​​​​G=0 or current through BD is zero.

So, answer is option (a)

Current through BD is zero and $V_{B}=V_{D}$
