Huh? The equipment does not "take" or "draw" anything. The electrical pressure of the source, called voltage, forces electrons through the load. Electrons per unit time are called current. The current is only limited by the resistance of the load, in accord with Ohms Law. The resistance of the load acts as a valve or choke point in the circuit, thus limiting the current. In the case Allan describes, the battery is the primary resistance in the circuit. If the battery was large enough and, or, sufficiently discharged (low resistance), and the source could provide enough current, the C-40 would "Toast".
Dick Ratico --- You wrote: Because it is not 80 amps current flowing, it is a capacity of 80 amps. Think of it this way. Your toaster is plugged into an outlet that is powered by the grid. The grid has infinite capacity. Why doesn't your toaster explode? Because it takes the current it needs. Now, increase the voltage and you may have a runaway current situation, but at the design voltage the equipment takes the current it needs up to the limit if the supply. --- end of quote --- _______________________________________________ List sponsored by Home Power magazine List Address: [email protected] Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
