When current passing through a coil increases, direction of induced emf is |
|
Answer» in the direction of existing current. `epsilon=-L(DI)/(DT)` Here current passing through the coil, increases with time and so `((dI)/(dt)) gt 0 rArr epsilon lt 0 rArr` self induced emf will be in a direction opposite to the flow of current, so that increase in the current through the coil can be OPPOSED, according to Lenz.s law. |
