Question

In a series LCR circuit the phase difference between the voltage and the current is 45° then the power factor will be
(a) 0.607 (b) 0.707 (c) 0.808 (d) 1​

Answer 1

Answer:

LCR are phase between voltage and current is 45° then the power factor will be 0.707

Answer 2

Answer:

b)0.707

Explanation:

We know ,

Power factor cos(fi) = True power/apparent power

We have 45°

Therefore cos45° is

$1 \div \sqrt{2}$

Hence, 0.707
