	1. Electric power and energy. Permanent and transient phenomena. Instance of permanent phenomenon; of transient; of combination of both. Transient as intermediary condition between permanents.
	2. Energy storage in electric circuit, by magnetic and dielectric field. Other energy storage. Change of stored energy as origin of transient.
	3. Transients existing with all forms of energy: transients of railway car; of fan motor; of incandescent lamp. Destructive values. High-speed water-power governing. Fundamental condition of transient. Electric transients simpler, their theory further advanced, of more direct industrial importance.
	4. Simplest transients: proportionality of cause and effect. Most electrical transients of this character. Discussion of simple transient of electric circuit. Exponential function as its expression. Coefficient of its exponent. Other transients: deceleration of ship.
	5. Two classes of transients: single-energy and double-energy transients. Instance of car acceleration; of low-voltage circuit; of pendulum; of condenser discharge through inductive circuit. Transients of more than two forms of energy.
	6. Permanent phenomena usually simpler than transients. Reduction of alternating-current phenomena to permanents by effective values and by symbolic method. Nonperiodic transients.
