Question

A single-phase load is supplied by a single-phase voltage source. If the current flowing from load to the source is $10\angle -{150}^{\circ }$ A and if the voltage at the load terminals is $100\angle {60}^{\circ }V$ then the

• A. load absorbs real power and delivers reactive power.
  
• B. load absorbs real power and absorbs reactive power
• C. laod delivers real power and delivers reactive power.
  
• D. laod delivers real power and absorbs reactive power .

Answer 1

The correct option is B load absorbs real power and absorbs reactive power


Complex power supplied by load
$S=V{I}^{\ast }$
$=\left(100\angle {60}^{\circ }\right)\left(10\angle {150}^{\circ }\right)$
$=-866.025-j500VA$
As supplied active and reactive power are negative.
Hence, Load absorbs active and reactive power both.
