This was the first patient controlled permanent pacemaker as the primary circuit consisted of an inducing coil supplied by a portable transistor which produced short pulses at adjustable intervals and intensity.
42.
Again, this is the same principle that applies in induction coupled devices, such as a transformer, which draws more power at the primary circuit, if power is drawn from the secondary circuit.
43.
The regulator concluded that PWR2 was " potentially vulnerable to a structural failure of the primary circuit ", which was a failure mode with significant safety hazards to crew and the public.

The problem was, when I turned it on the voltage would come arcing out from the light switch, which was only in the 6 volt DC primary circuit, and cause an excruciating shock.
46.
Another difference is that even though they decrease voltage, they do not increase current as found in wound electromagnetic transformers-an ampere drawn by the load is an ampere drawn from the primary circuit.
47.
The motherboard, also referred to as system board or main board, is the primary circuit board within a personal computer, and other major system components plug directly into it or via a cable.
48.
In the first two cases, although primary current continues to flow, it approaches a steady value equal to the supply voltage V b divided by the total resistance ( s ) R in the primary circuit.
49.
Deeds said Intel-made mother boards, or the primary circuit boards in computers, will include the necessary tuners and will be marketed in computer systems made by Compaq, Packard-Bell and other major PC makers by year's end.
50.
Replacing the transformer is relatively easy because there are only four wires to connect; two come from the transformer and connect to the primary circuit, the other two are the wires from the chimes and door bell.
