Question

if power factor = cos θ = 1 it means that​

Answer 1

It shows that the phase angle between current and voltage is zero

Power factor

• When we take the cosine of the angle between current and voltage. It is termed as power factor.

• The formula for the power factor is P = VI Cosθ

When is the power factor equal to 1?

• Since, we know that Cosθ=1 only, when the value of θ=0

• This can only happen when the angle between current and voltage is equal to zero.
