The correct answer is "directly proportional".
Объяснение
## Step 1Inductive reactance is a property of inductors in an AC circuit. It is the opposition to the flow of alternating current due to the inductor.## Step 2The inductive reactance is directly proportional to the frequency of the alternating current. This means that as the frequency increases, the inductive reactance also increases, and vice versa.## Step 3The formula for inductive reactance is given by:###
where
is the inductive reactance,
is the frequency of the AC, and
is the inductance.## Step 4From the formula, it can be seen that the inductive reactance
is directly proportional to the frequency
. This means that the inductive reactance increases with an increase in frequency and decreases with a decrease in frequency.
