Q.
In the circuit shown in figure, the current drawn from the battery is $4A.$ If $10\ \Omega$ resistor is replaced by $20\ \Omega$ resistor, then current drawn from the circuit will be
A) $1\ A$
B) $2\ A$
C) $3\ A$
D) $0\ A$
Explanation
(d) Given circuit is a balanced Wheatstone bridge circuit. So there will be no change in equivalent resistance. Hence no further current will be drawn
