In the series a.c circuit shown above, the p.d across the inductor is 8Vr.m.s and that across the resistor is 6Vr.m.s. The effective voltage is
  • A.
    2V
  • B.
    10V
  • C.
    14V
  • D.
    48V
Correct Answer: Option B
Explanation

The effective V =
√ VR2 + VL2 =
√ 62 + 82 =
√ 36 + 64 =
√ 100 
10V
