an impedance coil draws an apparent power 50-volt ampere and an active power of 40 watts solve for q factor

To solve for the Q factor, we need to know the reactive power of the impedance coil. The Q factor can be calculated using the following formula:

Q = |Reactive Power (Q)| / Active Power (P)

Given that the apparent power (S) is 50-volt ampere and the active power (P) is 40 watts, we can find the reactive power (Q).

Apparent power (S) is given by the formula:

S = √(P^2 + Q^2)

We can rearrange this formula to solve for reactive power (Q):

Q = √(S^2 - P^2)

Substituting the values, we have:

Q = √((50^2) - (40^2))
Q = √(2500 - 1600)
Q = √900
Q = 30

Therefore, the Q factor of the impedance coil is 30.
