Question

In the circuit shown in figure, the current drawn from the battery is $4A$. If $10\Omega$ resistor is replaced by $20\Omega$ resistor, the current drawn from the circuit will be

• A. $1A$
• B. $2A$
• C. $3A$
• D. $0A$

Answer 1

Answer: (D)

$0A$

Given circuit is a balanced Wheatstone bridge circuit. So there will be no change in equivalent resistance. Hence no further current will be drawn.
