What is the effect of increasing the frequency of AC on the inductive reactance? (2021)
Step 1: Understand what AC means. AC stands for Alternating Current, which is a type of electrical current that changes direction periodically.
Step 2: Learn about inductive reactance. Inductive reactance is the opposition that an inductor (a coil of wire) offers to the flow of AC. It is similar to resistance in a circuit.
Step 3: Know the formula for inductive reactance. The formula is XL = 2πfL, where XL is the inductive reactance, f is the frequency of the AC, and L is the inductance of the coil.
Step 4: Observe the relationship between frequency and inductive reactance. In the formula, you can see that XL is directly proportional to the frequency (f). This means that if the frequency increases, the inductive reactance (XL) also increases.
Step 5: Conclude that increasing the frequency of AC will lead to an increase in inductive reactance.
