In an ac circuit the current lags behind
Did you know?
WebWe see that the current lags in phase 90 behind the emf. The reason is that, if you suddenly apply an external voltage, the current takes a while to build up, because the induced magnetic eld opposes the buildup according to Lenz’s law. So, in an inductor the voltage leads the current. In the complex notation, this means that, if Ee(t) = E 0e ... http://hyperphysics.phy-astr.gsu.edu/hbase/electric/phase.html
