Question

In the circuit shown, calculate the current through 6 V battery. (A) (1/4) A (B) (1/8) A (C) (1/2) A (D) None of these

Equivalent circuit: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/9b2c7a6bf2a364f18298a9a76cb6f397-.png" /> I=(5-5/8)=0 ⇒ VA-VB=0 So current will be only in the smaller loop containing 6 V and 4 V battery. So current through 6 V battery, I prime=(6-4/4)=(1/2) A

Q. In the circuit shown, calculate the current through $6 V$ battery.

(1/4) A

(1/8) A

(1/2) A

None of these

Equivalent circuit:

$I = \frac{5 - 5}{8} = 0 \Rightarrow V_{A} - V_{B} = 0$
So current will be only in the smaller loop containing $6 V$ and $4 V$ battery. So current through $6 V$ battery,
$I^{'} = \frac{6 - 4}{4} = \frac{1}{2} A$

Q. In the circuit shown, calculate the current through 6V battery.
