the terminals of the condenser and the total voltage of 

 the circuit. For each set of readings construct a diagram 

 showing the relation between the voltages of the circuit, 

 proceeding as in the example given below. Hen6e cal- 

 culate the total power of the circuit and the power in the 

 inductive and non-inductive portions. 



Power and Voltages in Circuit with Capacity, Resistance, and 

 Self-induction. ' 



The method of drawing the diagram and determining 

 the phase relations between the voltages of the various 

 portions of the circuit are best discussed in connection 

 with an actual example. 



The readings tabulated in the annexed table show the 

 readings obtained in an experiment in which a 20 micro- 

 farad condenser formed the capacity, incandescent lamps 

 were used as the non-inductive resistance, and two sections 

 of a small transformer were employed as inductive resis- 

 tance. In this case a wattmeter was also used to check 

 the accuracy of the results. The figures given in brackets 

 are calculated values, the other figures were those actually 

 observed. 



It will be convenient to adopt a convention frequently 

 employed, of drawing energy voltage on the diagram
