Question

Find out the value of resistance R in figure. (A) 100 Ω (B) 200 Ω (C) 50 Ω (D) 150 Ω

Potential difference across C and D is 100 V. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/12aee1f67cbe26d05a9b8268d31f113f-.png" /> Hence, I1=(100/100)=1 A , VA C=120-100=20 V And I=(20/10)=2 A. Hence, I2=2-1=1 A R=100 / I2=100 Ω

Q. Find out the value of resistance $R$ in figure.

$100 Ω$

$200 Ω$

$50 Ω$

$150 Ω$

Potential difference across $C$ and $D$ is $100 V$ .

Hence, $I_{1} = \frac{100}{100} = 1 A, V_{A C} = 120 - 100 = 20 V$
And $I = \frac{20}{10} = 2 A$ . Hence, $I_{2} = 2 - 1 = 1 A$
$R = 100/ I_{2} = 100 Ω$
