WebCONCEPT:. Self-induction: Self-inductance is the property of the current-carrying coil that resists or opposes the change of current flowing through it.; This occurs mainly due to the self-induced emf produced in the coil itself. \(⇒ L=N\frac{ϕ}{I}\) Where N = number of turns in the coil, L = self-inductance of the coil, ϕ = flux associated with the coil and I = current … Webv. t. e. In electromagnetism and electronics, electromotive force (also electromotance, abbreviated emf, [1] [2] denoted or ) is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf [3] by converting other forms of energy into electrical energy. [3] how does hamza wash his hair
