Why current lag behind voltage in inductive load
Click For Summary
SUMMARY
In inductive loads, current lags behind voltage due to the nature of inductance, which creates a phase difference governed by the inductive reactance. This phase difference is described by the differential equations that relate voltage and current in inductors, specifically V = L(di/dt), where L is the inductance. Conversely, in capacitive loads, current leads voltage due to capacitive reactance, described by the equation I = C(dv/dt), where C is the capacitance. Understanding these relationships is crucial for analyzing AC circuits.
PREREQUISITES- Understanding of inductors and capacitors in electrical circuits
