Specific Resistance | Physics Of Conductors And Insulators
When the battery''s internal resistance, R DC, is 1 Ω, and the load, R, is 9 Ω, the battery outputs a voltage of 9 V. However, if the internal resistance increases to 2 Ω, the output voltage drops to approximately 8.2 V.
Lithium metal itself has the highest specific capacity (>3860 mAh∙g −1) and the lowest potential (−3.040 V), which should make it an ideal anode material []. However, lithium is a highly reactive metal and formally the relative volume expansion trivially becomes infinitely large in this case.
By monitoring changes in the DC internal resistance of a battery, it is possible to predict its lifespan. When the DC internal resistance reaches a certain level, it indicates that the battery''s lifespan is approaching …
Question: Q34: A certain electrical device has an unknown resistance. You have a available a 12 V battery and an ammeter. How would you determine the value of the unknown resistance? Draw the necessary circuit connections.
