QAIPM-2015-Ph-1317: NEET 2015 Physics - Class 12 AIPM-2015-Ph-1317 Solution: A resistance 'R' draws power 'P' when connected to an AC…

A resistance 'R' draws power 'P' when connected to an AC source. If an inductance is now placed in series with the resistance such that the impedance of the circuit becomes 'Z'. the power drawn will be P(RZ)P(\frac{R}{Z}) P P(RZ)2P(\frac{R}{Z})^2 PRZP\frac{R}{Z}

Multiple Choice Options

  • A P(RZ)P\left( {{R \over Z}} \right) P ( Z R _ )
  • B P
  • C P(RZ)2P{\left( {{R \over Z}} \right)^2} P ( Z R _ ) 2
  • D PRZP\sqrt {{R \over Z}} P Z R _ _
