Q. For what value of $R$ in circuit, current through $4 \,\Omega$ resistance is zero?
Current Electricity
A
$4\, \Omega$
B
$1 \,\Omega$
C
$3 \,\Omega$
D
$5\, \Omega$
Solution:
As current through ' $4 \,\Omega'$ ' is zero, there should be no potential drop across it.
Value of $R$ for this condition $=1 \,\Omega$
