| Question! | How does a capacitor and inductor behave like at high frequencies? |
| The answer! | an inductor acts as an open circuit at high frequencies (_____ o o _____)bcz its reactance ( XL = 2πfL ) increases with increasing frequency, offering significant opposition to the flow of AC.Thus, bhot high freq pr, its reactance (resistance) becomes infinity (no current can flow)A capacitor acts as connecting wire at high f (_______)bcz XC = 1/2πfC.... Thus, freq inc, => Xc decreaseAT very high freq it becomes almost zero, thus acts like no resistance in wire=> connecting wire |
