MCQ
Considering the following circuit, select the correct alternative
  • Power supplied by the battery is $300\ W$
  • B
    Current flowing in the circuit is $5\ A$
  • C
    Current in wire $AB$ is zero
  • D
    All of these

Answer

Correct option: A.
Power supplied by the battery is $300\ W$
a
Current won't pass through

$4\, \Omega $ and $ 6\, \Omega$

so $\mathrm{P}=\frac{(30)^{2}}{3}=300 \mathrm{\,W}$

$I=\frac{30}{3}=10 \mathrm{\,A}$
