What reading level is Alternating Currents of Electricity And the Theory of Transformers book?
To quickly assess the difficulty of the text, read a short excerpt:
22 component C H, exactly one quarter period in advance of C E, and therefore in phase with the eddy current com- ponent C s .
In fig. 22 let oe l represent the induced E. M. F. Then C E, the wattless component of the exciting VECTOR DIAGRAM FOR INDUCTIVE CIRCUIT 75 current, will have to be drawn 90 in advance of oe r Draw c s and C H (both opposite to e^ and add them together, to form c w, the total ' work ' component of the current. Now add the vectors C E and c w in the usual way, and draw o...c, which will represent the total current.
If J?=the ohmic resistance of the circuit, e^ the effective volts (in phase with c), will be equal to c x R. Add e. 2 and the vector e\ (exactly equal and opposite to e^, and draw oe, which will represent the necessary impressed potential difference in order that the current C may flow through the circuit.
It is interesting to compare fig. 22 with fig. 12 (p. 53). The current in fig. 12 (which applies to a circuit or choking coil without an iron or metal core) lags exactly 90 behind e\ ; whereas in fig.
