Question

For what value of R in the circuit as shown, current through $4\Omega$ will be zero:

• A. $1\Omega$
• B. $2\Omega$
• C. $3\Omega$
• D. $4\Omega$

Answer 1

The correct option is A $1\Omega$

$\begin{array}{c}\Rightarrow i=\frac{10-6}{2}=\frac{6-4}{R}\\ \Rightarrow 2=\frac{2}{R}\\ \Rightarrow R=1\Omega \\ Hence,\\ optionAiscorrectanswer.\end{array}$
