In a series circuit, voltages add up for all components connected in the circuit, and currents are the same through all components. In a parallel circuit, each device is directly connected to the power source, so each device receives the same voltage. The current in a parallel circuit flows...
Cliff found some 24 volt light bulbs, put them in parallel to make the load. A much less expensive way, but alas, the 24v screw base bulbs are getting more expensive and harder to find. Notice that Cliff used 4 little black things too. Those are thermistors, used to limit the inrush...
9.A system as in claim 8 where the first supervisory current allows the detection of high resistance parallel faults in the conductors. 10.A system as in claim 9 where a lower second supervisory current allows the detection of low resistance series faults in the conductors. ...
