What happens if one wires a Genecon hand-cranked generator across a large inductance and one turns the handle? To find out, I connected the Genecon depicted in Fig. 1 of Ref. 1 to a standard PASCO 3200-turn coil (roughly cubical at about 4 cm on a side). To increase the coil's inductance, I inserted a laminated iron bar (also available from PASCO) into its core. According to Fig. 2 of Ref. 1, the emf of a Genecon cranked at 1 Hz can be approximated as a sinusoidal ripple riding on top of a dc bias,

where , with . With the coil connected, Kirchhoff's loop rule implies
